Butadiene/styrene copolymer.

PetroFlex E-SBR 1027 is a butadiene/ styrene copolymer, produced by hot emulsion polymerization, using food grade fatty acid as the emulsifier, according to the company's product manual. To protect the polymer during the production and storage phases, a non-staining food grade BHT anti-oxidant 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 in the cis and vinyl configurations, according to the literature. The E-SBR product presents Mooney viscosity between 46 and 58 ML (1+4) at 100 [degrees] C, according to the manual. PetroFlex E-SBR 1027 is said to offer excellent sticking properties. Specifications are presented in the literature. (PetroFlex)
