Typical crystalline plastics are polyethylene, polypropylene, nylon, acetals, and thermoplastic polyesters. Typical amorphous plastics are polystyrene, acrylics, PVC, SAN, and ABS.

Chromatographic resolution is also dependent on column efficiency (i). Column efficiency is directly dependent on the nature of the support matrix and how well that support is packed in its column. Available chromatographic supports are based on dextran, agarose, polystyrene, acrylic, cellulose, silica gel and a variety of other polymers. Althou cellulosic supports are manufactured in both microcrystalline and leaded forms, most supports are beaded. Newer supports may use hybrid bead construction where the base support is coated with a second materid (e.g., dextran or silica coated with agarose).

The external effects of the environment on polymer blends are chemical in nature, and normally lead to degradation of the polymers. Chain scission, depolymerization and reactions on the side-chain substituents all contribute to overall deterioration of blend properties. These are described for blends containing polyvinyl chloride, polystyrene, acrylics and polyolefins mixed with a variety of other polymers. The general feamres of radiation damage and the detrimental effects of processing are reviewed. 

Any gas or vapour produced by burning is carefully smelled and recorded, bearing in mind that it may be toxic (polytetrafluoroethylene) or corrosive (cellulose acetate). The pH of any vapour generated is determined by holding Universal Indicator paper or pH indicator strips moistened with distilled water in its path. Plastics producing acidic vapours include cellulose nitrate and acetate, polyester, polyurethane, PVC. Those forming neutral vapours are polyethylene, polystyrene, acrylics, polycarbonate, silicones and epoxies. Alkaline products originate mainly from nylon and formaldehyde plastics. 

Common thermoplastics include polyethylene, polystyrene, acrylic, polyvinyl chloride, and polypropylene (see Figure 8-6). We can easily identify a plastic by looking at the recycling triangle symbol code found on each product. Polyethylene is made from natural gas. We use polyethylene for a variety of products such as milk cartons. Polystyrene provides an inexpensive...

Antioxidant an-te- ak-so-dont, ian- tI- (1926) n. A substance that slows down the oxidation of oils, fats, etc., and thus helps to check deterioration antioxidants are added commercially to foods, soaps, etc. Although the term technically applies to molecules reacting with oxygen, it is often applied to molecules that protect from any free radical molecule with unpaired electrons. Chemistry encyclopedia, www. ChemistryAbout.com. A substance incorporated in a material to inhibit oxidation at normal or elevated temperatures. Antioxidants are used mainly with natural and synthetic rubbers, petroleum-based resins, and other such polymers that oxidize readily due to structural unsaturation. However, some thermoplastics, namely polypropylene, ABS, rubber-modified polystyrene, acrylic and vinyl resins, also require protection by antioxidants for some uses. There are two main classes (1) Those inhibit oxidation by reacting with chain-propagating radicals, such as hindered phenols that intercept free radicals. These are called primary antioxidants or free-radical scavengers. (2) Those decompose peroxide into non-radical and stable products examples are phosphates and various sulfur compounds, e.g., esters of thiodipropionic acid. These are referred...

Latex la- teks [NS latic. latex, from L. fluid] (1835) (pi lattices or latexes) n. (1) An emulsion of a polymeric substance in an aqueous medium. (2) The sap of the hevea (rubber) tree and other plants, or emulsions prepared from the same. Latices of interest to the coatings and plastics industry are based mainly on styrene-butadiene co-polymers, polystyrene, acrylics, and vinyl polymers and co-polymers. (3) Fine dispersion of rubber or resin, natural or synthetic, in water the synthetic is made by emulsion polymerization. Latex and emulsion are often used synonymously in the paint industry. Emulsified monomers once polymerized become solids or plasticized gel particles and not emulsions but aqueous suspensions.

Maximum dimensional stability is afforded by mineral-filled phenolics. Although the thermoplastics as a whole are weak in this respect, polystyrene, acrylic, rigid vinyls, and ethyl cellulose are exceptions, having satisfactory dimensional stability for many applications where the requirements are not of the severest order.
