Abstract
Embodiments of the present disclosure are directed to partially crosslinked polymer system including a vulcanized, silane grafted thermoplastic elastomer and carbon-carbon bond crosslinks. The vulcanized, silane grafted thermoplastic elastomer comprises a polymerized reaction product of vinyl aromatic monomeric units and conjugated diene monomeric units.

A process for making a partially crosslinked polymer system comprising a crosslinked reaction product of a thermoplastic elastomer comprising vinyl aromatic monomeric units and conjugated diene monomeric units and a vulcanization package comprising an organic peroxide and a silane, the process comprising the steps of:
- blending the thermoplastic elastomer, the organic peroxide, and the silane such that the thermoplastic elastomer includes carbon-carbon bond crosslinks and grafted silane moieties;
- and
- extruding the carbon-carbon crosslinked, silane-grafted blend.
