合成了三个新茂钛催化剂:茂基三呋喃甲氧基钛,茂基三(四氢呋喃甲氧基)钛,茂基三苄氧基钛,其结构均经元素分析、^1HNMR、^1^3CNMR、IR及MS确证。它们与甲基铝氧烷(MAO)组成的催化体系对苯乙烯间规均聚合有良好的催化活性。

关键词: 间规聚合, 苯乙烯, 四氢呋喃, 钛催化剂, 元素分析

Three new titanocene catalysts η^5-cyclopentadienyltri (tetrahydro- furfuryloxyl) titanium, η^5-cyclopentadienyl trifurfuryloxyl titanium, η^5-cyclopentadienyl tribenzyloxyl-titanium were synthesized and characterized by elementary analysis、FTIR、^1H NMR、^1^3C NMR and MS methods. The syndiotactic polymerization of styrene with these three titanocene catalysts were investigated.

Key words: TITANIUM CATALYST, STYRENE, ELEMENTAL ANALYSIS, TETRAHYDROFURAN
