沈阳化工大学在三元乙丙橡胶(EPDM)/聚丙烯(PP)并用体系中,通过氧化锌与马来酸进行原位生成,改善EPDM与PP的界面键合性,提高并用体系物理性能。硫化过程中,在引发剂DCP的作用下,氧化锌与马来酸在并用体系中发生原位合成反应,生成不饱和羧酸金属盐马来酸锌,并分别与EPDM和PP交联,在并用体系中形成网 Shenyang University of Chemical Technology In EPDM / PP blends, the in-situ formation of zinc oxide and maleic acid can improve the interfacial bonding between EPDM and PP and improve the physical properties of the blends. During the vulcanization, under the action of initiator DCP, the in-situ synthesis of zinc oxide and maleic acid occurred in the combined system to form the unsaturated carboxylic acid metal salt of maleic acid and crosslinked with EPDM and PP respectively. And use the system to form a network
