Zusammenfassung:Thermoplastic vulcanizates (TPVs) may comprise a vulcanizable elastomer rubber, a thermoplastic polymer, and a plasticizer, wherein the plasticizer comprises a solid resin. Methods include introducing to a blender a masterbatch comprising a first thermoplastic polymer and a curative, a vulcanizable elastomer rubber, a second thermoplastic polymer, and 25 parts to 250 parts of a plasticizer by weight of the vulcanizable elastomer rubber. The first and second thermoplastic polymers combined are 20 parts to 250 parts by weight of the vulcanizable elastomer rubber, and the plasticizer comprises a solid resin. The masterbatch, thermoplastic resin, and plasticizer are then dynamically vulcanized in at least a portion of the vulcanizable elastomer rubber to form a thermoplastic vulcanizate.
