摘要
用OsO_4对聚丁二烯-α-甲基苯乙烯阳离子接枝共聚物进行氧化断链,剖析了接枝共聚反应体系,并测定其支链和均聚物的分子量。使用透射电镜和示差扫描量热仪对接枝共聚物的微相结构进行了研究。测定了含不同量1,2结构的聚丁二烯接枝共聚物的拉伸力学性能。
Molecular weight of graft chain of cationic graft copolymer PB-g-MS and thehomopolymer are investigated by oxidation of PB backbone with OsO_4. Microphasestructure of the copolymer are observed with DSC and TEM. Elastomeric propertiesof the copolymer are determined by tensile test.
