| 摘 要： | 采用活性阴离子聚合技术,以BuLi为引发剂,DVB为偶联剂,在环己烷体系中合成了星形多官能团大分子PS-b-PI.然后以此星形大分子作为接枝剂,通过阳离子聚合,合成了一种在每个星形大分子的臂上接枝几个聚异丁烯的新型支化聚合物,并对其进行了GPC、1H-NMR、FT-IR等分析表征,讨论了不同的加料顺序对其的影响,1H-NMR结果表明其接枝效率达80%左右. |
| 关 键 词： | 阴离子聚合 阳离子聚合 星形大分子 支化聚合物 接枝 |

| Abstract: | A star-shaped multifunctional styrene-isoprene copolymer was synthesized in the present of n-BuLi as initiator, divinyl benzene as coupling agent, cyclohexane as solvent by living anionic polymerization. Then using this polymer as grafting agent, a novel branched polymer that each arm of star-shaped PS-b-PI contained several polyisobutylene was prepared via cationic poly- merization. The star PS-b-PI and star-branched polyisobutylene were characterized by GPC, ^1H- NMR and FT-IR, and the effect of different adding order was investigated. The ^1H-NMR results show that the grafting efficiency is about 80%. |
| Keywords: | anionic polymerization cationic polymerization star-shaped polymer branched polymer graft |
