| 摘 要： | 采用溶液法将极性单体马来酸酐在隔氧条件下对聚丁二烯进行接枝，通过氢化反应及马来酸酐与端羟基PMMA的酯化反应，合成了氢化聚丁二烯／聚甲基丙烯酸甲酯接枝共聚物。考察了反应时间等因素对接枝反应的影响，测定了聚合物的接枝率，同时对其结构进行了表征。结果表明，所合成的接枝共聚物具有良好耐热性和表面迁移特性，适合用作PP的太分子表面改性剂。

| Abstract: | Polar monomer MA was grafted onto polybutadiene in the presence of nitrogen by means of solution method,and a macromolecular surface modifier,the copolymer of hydrogenated polybutadiene grafted with poly(methyl methylacrylate)(HPB-g-PMMA) was synthesized by hydrogenation and esterification of polybutadiene with TSH and hydroxyl-terminated poly(methyl methylacrylate).The effects of the reaction time and other conditions on the graft reaction were studied,the graft efficiency was determined and graft copolymer was characterized.The results indicated that HPB-g-PMMA had good heat resistance,could diffuse preferably onto the surface of blends and be used as surface modifier for PP. |
