摘　　要：采用反应注射成型工艺,使用钨系双组分催化剂WCl6/Et2AlCl进行双环戊二烯单体原位聚合反应,制备出聚双环戊二烯/聚苯乙烯/蒙脱土(PDCPD/PS/MMT)纳米复合材料。运用XRD、SEM对聚合物进行表征,测定了其拉伸强度、冲击强度及弯曲强度等力学性能。结果表明:MMT片层被完全剥离开,形成了真正的纳米复合材料,PS、MMT质量分数分别为1%、2%时,纳米复合材料的各项性能最好。By means of reaction injecting molding,polydicyclopentadiene/polystyrene/montmorillonite（PDCPD/PS/MMT）nanocomposite was polymerized by in-situ polymerization,using the catalytic system of WCl6/Et2AlCl.The synthetic polymer was characterized by means of XRD and SEM,tested the tensile strength,the flexural strength and the notched impact strength.The results revealed that MMT layers were completely peeled off,forming true nanocomposite materials.The best property of PDCPD/PS/MMT nanocomposite was obtained when the mass fraction of PS was 1% and MMT was 2%.
