摘要:
Described herein are thermoplastic vulcanizates comprising propylene-based elastomers and methods for producing the same. The thermoplastic vulcanizates comprise rubber, at least 10 wt% of thermoplastic resin, from 1 to 9 wt% of propylene-based elastomer, oil, and at least 5 wt% of one or more fillers. The thermoplastic vulcanizates are made by a method where the propylene-based elastomer is introduced to the extrusion reactor before the curative is introduced to the extrusion reactor.
