摘要
合成了相对分子质量为(0.21~4.41)×104的聚甲基丙烯酸甲酯大单体(MaMMA),并与CR进行接枝改性反应。实验结果表明,接枝率随着引发剂浓度及反应时间的增加而提高,其最大值为4.1%。当MaMMA相对分子质量为(0.61~1.13)×l04时,其接枝改性物对布基软质聚氯乙烯的剥离强度最大。
The poly(methyl methacrylate)macromonomers (MaMMA)of different molecular weight were synthesized and the graft modification of chloroprene rubber(CR)with MaMMA was investigated.The results showed that the graft rate increased with the increase of initiator concentration and reaction time,with a maximum value of 4%.The peel strength for the bonding to soft poly(vinylchoride)sheet reached its maximum value when the molecular weight of MaMMA was(0.61~1.13)×104.
