Butadiene/styrene copolymer.Butadiene/styrene copolymer copolymer: see polymer. . E-SBR 1028, described in the company's product manual, is a butadiene/ styrene sty·rene n. A colorless oily liquid from which polystyrenes, plastics, and synthetic rubber are produced. Also called vinylbenzene. copolymer produced by hot emulsion polymerization using food grade fatty acid as emulsifier emulsifier /emul·si·fi·er/ (e-mul´si-fi?er) an agent used to produce an emulsion. e·mul·si·fi·er n. An agent used to make an emulsion of a fixed oil. . To protect the polymer during the production and storage phases, a non-staining food grade BHT BHT butylated hydroxytoluene, an antioxidant used in foods, cosmetics, pharmaceuticals, and petroleum products. BHT n. A crystalline phenolic antioxidant used to preserve fats and oils, especially in foods. antioxidant is used. The monomers are randomly distributed in the polymer structure, while the butadiene fraction is found in its major part in the trans configuration, with a smaller fraction the cis and vinyl configurations, according to the literature. E-SBR 1028 presents Mooney viscosity between 52 and 64 ML (1+4) at 100 [degrees] C. Properties, polymer characteristics and applications are presented in the product manual.
