    • A process for making a thermoplastic vulcanizate includes blending a thermoplastic first polymer, an elastomeric second polymer, a carboxylic anhydride, a free radical generator, and a particulate reinforcing material to provide a first blend containing the thermoplastic first polymer and grafted elastomeric second polymer with the particulate reinforcing material dispersed therein, the particulate reinforcing material having sufficient surface moisture to permit coupling to the thermoplastic first polymer and the elastomeric second polymer upon reaction with a coupling agent; then, combining a coupling agent with the first blend for coupling the thermoplastic first polymer and/or grafted elastomeric second polymer with the particulate reinforcing material and/or crosslinking the grafted elastomeric second polymer.
    • 制备热塑性硫化橡胶的方法包括共混热塑性第一聚合物,弹性体第二聚合物,羧酸酐,自由基发生剂和颗粒增强材料,以提供含有热塑性第一聚合物和接枝的弹性体第二聚合物的第一共混物, 颗粒增强材料分散在其中,颗粒增强材料具有足够的表面水分,以允许当与偶联剂反应时与热塑性第一聚合物和弹性体第二聚合物偶联; 然后,将偶联剂与第一混合物结合,以将热塑性第一聚合物和/或接枝的弹性体第二聚合物与颗粒增强材料结合和/或交联接枝的弹性体第二聚合物。
