Abstract
A thermoplastic elastomer composition is provided. The composition comprises a hydrogenated elastomeric block copolymer having at least two resinous endblocks of polymerized monovinyl aromatic compound and an elastomeric midblock of polymerized conjugated diene, a midblock plasticizer, and an ethylene-propylene-diene monomer rubber grafted with styrene-acrylonitrile. The thermoplastic elastomer exhibits improved overmolding adhesion to polar matrices over compositions not containing the monomer rubber.
