Polyethylene terephthalate trade name

Polyethylene terephthalate [25038-59-9] (8) is a polyester produced by the condensation polymerization of dimethyl terephthalate and ethylene glycol. Polyethylene terephthalate sutures are available white (undyed), or dyed green with D C Green No. 6, or blue with D C Blue No. 6. These may be coated with polybutylene adipate (polybutilate), polyydimethylsiloxane, or polytetrafiuoroethylene [9002-84-0]. The sutures are distributed under the trade names Ethibond Exel, Mersdene, Polydek, Silky II Polydek, Surgidac, Tevdek II, Polyester, and Tl.Cron. 

Nylon-6 [25038-54-4] (9) is made by the bulk addition polymerization of caprolactam. Monofilament Nylon-6 sutures are avadable undyed (clear), or in post-dyed black (with logwood extract), blue (ED C Blue No. 2), or green (D C Green No. 5). Monofilament nylon-6 sutures are sold under the trade names Ethilon and Monosof monofilament nylon-6,6 sutures, under the trade names Dermalon and Ophthalon and monofilament polyethylene terephthalate sutures, under the trade name Surgidac. 

The most generally useful polyester is that made by reaction between dimethyl terephthalate (dimethyl 1,4-benzenedicarboxylate) and ethylene glycol (1,2-ethanediol). The product is used under the trade name Dacron to make clothing fiber and tire cord and under the name Mylar to make recording tape. The tensile strength of polyethylene terephthalate) film is nearly equal to that of steel. 

Perhaps the most important polyester is polyethylene terephthalate), commonly known as PET (or PETE 1 on plastic beverage bottles). The annual production of PET in the United States is of the order of 108 kg (105 metric tons). Much of this is converted into fabric (trade name, Dacron) or magnetically coated film (Mylar). 

The trade name of a polyester fibre used as textile reinforcement for mbber in products such as tyres, belting and hose. It is a truly synthetic fibre made from polyethylene terephthalate, a condensation product of terephthalic acid and ethylene glycol. 

Most of the polymers are better known by their trivial names or trade names. Polymers prepared from single polymers are denoted by prefixing poly- to the name of the monomer, e.g., polyethylene, polypropylene, Polyacrylonitrile, polystyrene, etc. If the monomer has substituents or has a multi-worded name, the name of the monomer is enclosed in parenthesis after the prefix poly-, e.g., poly (methyl methacrylate), poly (vinyl alcohol), etc. Condensation polymers like that derived from ethylene glycol and terephthalic acid are named as poly (ethylene terephthalate). 

The remarkable increase in the Melting point of polyesters formed by the incorporation of the aromatic ring is because of the stiffening of the polymer backbone. Thus, a polyester like polyethylene terephthalate (PETP) has a high Melting point due to the presence of the aromatic ring and is commercially the most popular polymers marketed under the trade name of Terylene or Terene.

Polyethylene terephthalate) in short PET is a polyester. It is mainly used in the garment industry with or without natural cotton and has trade names such as Terylene , Dacron , etc. As the name indicates, it is a polymer between terephthalic acid (PT) and ethylene glycol. Both terephthalic acid and dimethyl terephthalate (DMT) can be used to make the polymer. A majority of the modem plants tend to use PT as the starting material because of the availability of high-purity PT on a large scale. Both PT and DMT are first converted to bis(hydroxy ethyl) terephthalate 8.17 (see reaction 8.26). For PT this is effected by a straightforward esterification reaction. For DMT a transesterification reaction catalyzed by zinc and manganese acetate is used. 

Propanediol (1,3PD) is also undergoing a transition from a small-volume specialty chemical into a commodity. The driving force is its application in poly (trimethylene terephthalate) (PTT), which is expected to partially replace polyethylene terephthalate) and polyamide because of its better performance, such as stretch recovery. The projected market volume of PTT under the trade-names CORTERRA (Shell) and Sorona 3GT (Dupont) is 1 Mt a-1 within a few years. In consequence, the production volume of 1,3PD is expected to expand from 55kta-1 in 1999 to 360 kt a-1 in the near future. 1,3PD used to be synthesized from acrolein by Degussa and from ethylene oxide by Shell (see Fig. 8.8) but a fermentative process is now joining the competition. 

Polyester fibers, similar to polyamide fibers, represent another important family of fiber. Polyester fiber was discovered in England in 1941 and commercialized in 1950. Two common trade names of polyester are Dacron in the US and Terylene in the UK. The term polyester fiber represents a family of fibers made of polyethylene terephthalate. Dimethyl terephthalate is reacted with ethylene glycol in the presence of a catalyst, antimony oxide, to produce polyethylene terephthalate or polyester. The chain repeat structure of PET is given in Fig. 4.6. Although polyesters can be both thermosetting and thermoplastic, the term polyester has become synonymous with PET. Note that the PET chain structure is different from the simpler structure of nylon or polyethylene. In PET, the aromatic ring and its associated C-C bonds provide a rigidity to the structure. The polyester structure is also bulkier than that of nylon or polyethylene. These factors make polyester less flexible than nylon and polyethylene, and the crystallization rate of PET slower than that of nylon or polyethylene. Thus, when polyester is cooled from the melt, an appreciable amount of crystallization does not result. 

Polyesters constitute a second major class of condensation polymers. The most common polyester is polyethylene terephthalate (PET), which is sold under a variety of trade names (Dacron, Terylene, and Mylar) depending on its use. 

Further reaction and water removal from this system will ultimately give polyethylene terephthalate, well known commercially in fiber form as Dacron, or Terylene, and as a film by the Mylar trade name (Eq. 20.5).

Mylar mi- lar tradename Polyester (film). DuPont s registered trade name for biaxial-ly oriented film composed of polyethylene glycol terephthalate. 

In 1926, United States-based E.I. du Pont de Nemours and Co. initiated research in the field of very large molecules and synthetic fibers. This early research, headed by W.H. Carothers, concentrated on polymer which became nylon, the first synthetic fiber. Soon after, in the years 1939 1, John Rex Whinfield and James Tennant Dickson, employees of the Calico Printer s Association of Manchester, patented "polyethylene terephthalate" (also called PET or PETE) in 1941. Polyethylene terephthalate is the basis of synthetic fibers such as polyester, dacron, and terylene. In 1946, du Pont purchased the right to produce this polyester fiber in the United States. The company conducted some further developmental work, and in 1951, began to market the fiber under the name Dacron. Dupont s polyester research led to a whole range of trade-marked products, such as Mylar (1952), which is an extraordinarily strong polyester (PET) film, and others. 

This polymer, polyethylene terephthalate (PET), exhibits multiple ester linkages and is therefore called a polyester. PET is sold under many trade names, including Dacron and Mylar . It is primarily used in the manufacture of clothing. There are many different kinds of polyamides and polyesters, serving a variety of purposes. Kevlar, for example, is stronger than steel and is used in bulletproof vests ... 

Trade names are also widely used in synthetic fibers. For example, polyethylene terephthalate is called Dacron polypropylene, polypropylene fiber polyacrylonitrile, Acrylon poly(vinyl chloride), chloro fiber and polyamide, nylon. The numbers following the word nylon have different meanings ... 

Polyethylene terephthalate (PET) is a synthetic polymer formed by the reaction of ethylene glycol (HOCH2CH2OH) and terephthalic acid. Because PET is lightweight and impervious to air and moisture, it is commonly used for transparent soft drink containers. PET is also used to produce synthetic fibers, sold under the trade name of Dacron. Of the six most common synthetic polymers, PET is the most easily recycled, in part because beverage bottles that bear the recycling code "1" are composed almost entirely of PET. Recycled polyethylene terephthalate is used for fleece clothing and carpeting. In Chapter 30, we learn about the preparation and properties of synthetic polymers like polyethylene terephthalate. 

Many polymer films have been examined as capacitor dielectrics but those principally used are polyethylene terephthalate, polystyrene, polycarbonate, polytetrafluoroethylene, polyimides and polypara-xylylene. A number of these materials are more familiar by their trade names ... 

Common trade names for polyethylene terephthalate polyester are Monsanto, Dacron, Encron, Kadel IV, Polar Guard, Trevira, Fortrel, and Vycion. This polyester is an inexpensive fiber with a unique set of desirable properties which have made it useful in a wide range of end-use appl ica-tions. It has adequate aesthetic properties and bright translucent appearance unless a delusterant has been added to the fiber. The hand of the fiber is somewhat stiff unless the fiber has been texturized or modified, and fabrics from polyester exhibit moderate draping qualities. 

IntegRex A process for making polyethylene terephthalate, developed by Eastman Chemical, announced in 2004. It integrates the PX-PTA process with the PTA-PET process. It uses an aqueous solution of tere-phthalic acid instead of the solid acid. Johnson Matthey has developed a special catalyst for it. The first plant was built in S. Carolina in 2006. There was a patent dispute between Eastman Chemical and Wellman regarding the resin product, trade named ParaStar. The process was sold to DAK Americas in 2011 who licensed it to Alpek in 2013.
