无规聚丙烯改性研究

Studies on the modification of random polypropylene

无规聚丙烯氯化后,与丙烯腈、苯乙烯、丙烯酸丁酯按比例混合,在适当溶剂中进行热压本体悬浮聚合,得到接枝共聚物,抗冲击强度达275kg·cm/cm2,抗张强度417kg/cm2,是一种新型热塑性工程塑料.

The graft copolymer was produced by mixture of random polypropylene chloride,acrylonitrile and styrene butyl acrylate with the hotpressing suspension bulk polymerization in solvent.The copolymer obtained has the impact strength of 275 kg·cm/cm2 and the tensile strength of 417 kg/cm2.
