摘　　要：采用溶液法以多元单体接枝共聚氯化聚丙烯(CPP),制得氯化聚丙烯的多元共聚物。在不同的施工条件下,研究讨论了该多元共聚物对不锈钢(SUS)/聚丙烯(PP)复合结构材料的粘结作用。结果表明:该多元共聚物对SUS/PP复合结构材料具有良好的粘结作用,其最大剥离强度可达11.98 N/mm;该多元共聚物对SUS/PP的粘结作用具有良好的耐候性及耐水性,经冷热循环试验及50℃水浸泡60 h,未见粘结强度明显下降。A multiply copolymerized chlorinated polypropylene was prepared by means of solution method with multiple monomers grafted to chlorinated polypropylene（CPP）. The adhesion of that multiply copolymer to the kind of stainless steel（SUS）/polypropylene（PP） composite structure material was investigated in different execution conditions. The results showed that it had strong adhesion to SUS/PP as the peeling strength of resulted adhesive reached 11.98 N/mm. The weathering resistance and water resistance of the adhesion to SUS/PP was high, the significant debonding did not occur after thermal cycling test or immersed in 50 ℃ water for 60 h.
