摘　　要：研究了马来酸酐接枝聚丙烯(MP)、氯化聚丙烯(CPP)以及端胺基液体丁腈橡胶(ATBN)和马来酸酐接枝聚丙烯复合增容剂对NBR/PP共混体系的增容效果。采用溴化树脂体系、酚醛树脂体系和DCP体系,分别对共混体系的动态硫化效果进行了讨论。研究了DOP和聚酯对共混体系的增塑效果及耐油效果的影响。对TPV的相态结构、力学性能和耐热油性能研究表明:用ATBN/MP增容的共混体系经酚醛树脂动态硫化后,可以获得相态结构精细、性能优异的TPV;聚酯增塑剂是NBR/PP共混体系的一种比较理想的增塑剂。The effects of various compatibilizers, such as maleicmodified polypropylene(MP), chlorinated polypropylene(CPP), amineterminated liquid NBR(ATBN) and maleicmodified polypropylene(ATBN/MP)on NBR/PP blends system were investigated. The effects of dynamic vulcanization of NBR/PP blend were investigated in three kinds of vulcanization systems (sp1056, phenolic resin and DCP), respectively. And the effect of plasticization and hotoil resistance were also investigated with the introduction of plasticizer DOP and polyester into NBR/PP blend. The study on the morphology, mechanical properties and hotoilresistance properties showed that fine morphology and outstanding properties can be achieved when the blend was compatibilized by ATBN/MP and cured by phenolic resin; and polyester was a desired plasticizer for NBR/PP blend.
