Poly PETG

Polyester sheet products may be produced from amorphous poly(ethylene terephalate) (PET) or partiaHy crystallized PET. Acid-modified (PETA) and glycol modified (PETG) resins are used to make ultraclear sheet for packaging. Poly(butylene terephthalate) (PBT) has also been used in sheet form. Liquid-crystal polyester resins are recent entries into the market for specialty sheet. They exhibit great strength, dimensional stabHity, and inertness at temperatures above 250°C (see Polyesters,thermoplastic). [Pg.377]

PCT, PETG, PCTG and PCTAs can all be prepared readily via standard melt-phase poly condensation processes [34, 35], The diacid can be delivered via transesterification of the dimethyl esters or via direct esterification of the diacids. Numerous conventional catalyst and catalyst combinations can be employed. The use of a catalyst or catalyst combination is important for the manufacture of polyesters via the melt-phase process and has been well reported in the literature [36-41], Appropriate catalyst systems enable the production of polyesters with high processing rates and high molecular... [Pg.272]

Polyelectrolyte multilayers (PEM) have been used to alter surface charges, thus controlling the direction of EOF in chips made of PS [155,216,416], PMMA [216], and PETG [416]. PEM deposition was carried out by exposing the micro-channel alternatively to solutions of positively charged PEM poly(allylamine hydrochloride) PAAH and negatively charged PEM-poly(styrene sulfonate), or... [Pg.69]

Anionic polymerization of EtG leads to a new synthetic biodegradable polymer, namely poly(ethyl glyoxylate). Because of a low ceiling temperature and transfer reactions, PEtG has hydroxyl ends that can be end-capped with phenyl isocyanate. [Pg.78]

Three polymer sheets of poly(methyI methacrylate) (PMMA), polyethylene terephthalate glycol modified (PETG) and polyethylene terephthalate (PET) were used. These polymers are all transparent with thicknesses of 1.5, 1.0 and 0.26 mm, respectively. Couponshaped samples of 1 4 cm were made from all three polymers and... [Pg.143]

Systematic study of the mechanism of formation of the 3-D network in the case of polymer blends with H-bonding demonstrated that this process takes place in the melt before the drawing step, and the subsequent cold drawing results in drastic reduction of the diameters of the network elements. This conclusion was proved by SEM observation of melt blended samples taken immediately after the extruder die. They were treated with water in order to extract the PVA and analyzed by SEM. A blend of PVA with glycol-modified poly(ethylene terephthalate) (PETG) was used for these experiments. [Pg.228]

Udipi [2] has discovered that polymer blends comprising a PC, amorphous polyester such as PETG, poly(ethylene terepthalate), and a nitrile rubber can form an alloy with superior balance of properties. Improved melt flow and spiral flow was demonstrated in injection molding applications. Udipi prepared a polymer alloy with 30% aromatic polycarbonate, 30% of PETG made of a condensation copolymer of terepthalic acid and a mixture of ethylene glycol and 1,4-cyclohexanedimethanol, and 3% nitrile rubber. This blend has a spiral flow of 27 cm, heat distortion temperature of 75°C, and Izod impact resistance of 130 J/m. [Pg.168]

Figure 13.34 (90) illustrates oxygen permeability for poly(ethylene tereph-thalate), PET, amorphous glycol modified PET, PETG, and poly(ethylene naphthalate), PEN. The PETG composition is similar to that described in Table 4.5, and widely used for soft drinks. [Pg.734]

PETG is glycol-modified poly(ethylene terephthalate), PET is poly(ethylene terephthalate), and PEN is poly(ethylene naphthalate). The effective aspect ratio of these composites is in the range of 150-200.
