摘　　要：双烷基过氧化物在短支链助交联剂的配合下,使乙丙二元共聚丙烯和长支链的乙-辛烯共聚物产生网状交联结构。β成核剂,接枝处理过的CaCO3 母粒,在该体系中产生协作效应,保证专用料达到高中档聚丙烯汽车专用料要求。Crosslinked network structure of COPP and POES with long branched chain was formed by the combination effect of double alkyl peroxide and auxiliary crosslinking agent with short branched chain. β-nucleating agent and grafted CaCO_3 masterbathes had synergistic effect in the compound, which ensured the compound to meet the needs for high and median levels of special compounds for car bumper.
