Abstract

The propensity of a half-sandwich (η⁵-tetramethylcyclopentadienyl) dimethylsilylamido Ti(IV)-based catalyst bearing an auxiliary diethylboryl-protected pyridyl moiety (Ti-8), activated by methylaluminoxane (MAO) to homopolymerize α-olefins such as ethylene, 1-hexene and styrene as well as to copolymerize styrene with 1,3-cyclo-hexadiene is described. The reactivity of Ti-8 was investigated in comparison to a 6-(2-(diethylboryl)phenyl)pyrid-2-yl-free analogue (Ti-3).

摘要

一种由半夹心（η⁵-四甲基环戊二烯基）二甲基硅氨基 Ti(IV)基催化剂组成的聚合催化剂，该催化剂带有辅助的二乙基硼保护吡啶部分（Ti-8），通过甲基铝氧烷（MAO）激活，可均聚α-烯烃，如乙烯、1-己烯和苯乙烯，以及与 1,3-环己二烯共聚。与没有 6-(2-(二乙基硼基)苯基)吡啶-2-基的类似物（Ti-3）相比，研究了 Ti-8 的反应性。
