| 中文摘要: |
| 研究了PVC、氯化聚乙烯(CPE)、氯化橡胶(CLR)及氯化聚氯乙烯(CPVC)等高氯聚合物(HCCP)对甲基丙烯酸甲酯与CR接枝共聚反应的影响。结果表明：HCCP可加快反应速率，提高接枝效率。加快反应速率的能力随HCCP中的β-H原子数量的增大而增大，其顺序为PVC>CPE>CLR>CPVC；添加HCCP后接枝共聚物的拉伸强度、撕裂强度和粘合强度均有大幅度提高。 |
| 英文摘要: |
| The influence of HCCP(high chlorine content polymer)such as PVC，CPE，CLR and CPVC on MMA(methyl methacrylate)/CR graft copolymerization was investigated.The results showed that HCCP accelerated the reaction rate and increased the graft efficiency；as the β-H amount in HCCP increased，the reaction rate speeded up in the order of PVC>CPE>CLR>CPVC；the tensile strength，tear strength and adhesion of the graft copolymer improved significantly by adding HCCP in copolymerization. |
