Thermoplastic elastomer compositions and process for the preparation thereof

摘要: Thermoplastic elastomer composition characterized by excellent oil resistance while preserving high tear and tension pull comprises non-functionalized block copolymer of aromatic vinyl compound conjugated diene or selectively hydrogenated product thereof (e.g. styrene-butadiene-styrene copolymer), rubber polymer having at least one functional group selected from the consisting carboxyl, amino, epoxy hydroxyl acrylonitrile-butadiene containing a carboxyl as reactive group), which is with polystyrene 1% weight oxazolinyl when copolymer).
