摘要
本文介绍了Kennedy及其共同工作者首次由阳离子合成新型芳香族和脂肪族的大试剂(macroreagents),特别是带有Si—Cl和Si—H活性端基的聚α-甲基苯乙烯与聚异丁烯。这些含有化学活性的Si—Cl和Si—H键的聚烯烃具有优良的物理性能,可用于制备嵌段与接枝共聚物。
This paper presents the works of Kennedy, J.P. and his colleagues that they prepared the new aromatic and aliphatic macroreagents for the first time by cationic synthesis way, especially they synthesised poly (α-methylstyrenes)and polyisobutylenes and both of which are carrying with Si-Cl and Si-H reactive head groups. These versatile polyhydrocarbons possess excellent physical properties and chemical reactivity of Si-Cl and Si-H bonds. These polymers may be used for preparation of block and graft copolymers.
