    摘要： In one embodiment is a thermoplastic vulcanizates having improved extrusion properties formed from a composition that includes from 20% to about 80% by weight of an elastomer, from about 80% to about 20% by weight of a thermoplastic, from about 0.05 to about 12 phr of a multifunctional methacrylate monomer peroxide curing coagent; and from about 0.02 to about 6 phr of a phosphorous containing stabilizer. The resultant thermoplastic vulcanizate may be cured with a peroxide curing agent and shows improved die lip build up compared to conventionally prepared thermoplastic vulcanizates. Methods of forming thermoplastic vulcanizates having improved die lip build up are also taught.
