THERMOPLASTIC POLYMER COMPOSITIONS

Abstract: the disclosure relates to a thermoplastic polymer composition comprising: an epoxidized product of a hydrogenated styrenic block copolymer (hsbc), an engineering thermoplastic, optionally an oil extended hsbc, and optional additives. the hsbc includes at least one block “s” composed of vinyl aromatic units and at least one block “r” composed of hydrogenated diene units. the epoxidized hsbc contains 1 to 35 wt. % epoxy functional groups and has a residual unsaturation (ru) of 0.05 to 20 meq/g. this thermoplastic polymer composition offers improved impact resistance and processability and is suitable for producing molded articles.
