合成了ＣｐＴｉＣｌ３／ＭＡＯ、Ｃｐ＊ＴｉＣｌ３／ＭＡＯ、Ｃｐ＊Ｔｉ（ＯＣＨ２ＣＨＣＨ２）３／ＭＡＯ和Ｃｐ＊Ｔｉ（ＯＭｅ）３／ＭＡＯ四种均相催化体系．结果发现，［Ｃｐ＊Ｔｉ（ＯＣＨ２ＣＨＣＨ２）３］／甲基铝氧烷（ＭＡＯ）催化体系热稳定性较高，在３３３～３６３Ｋ下进行苯乙烯间规聚合具有最高的催化活性；聚合反应产物用沸丁酮抽提８ｈ，不溶部分间规聚苯乙烯（ｓＰＳ）占总聚合产物重量的９８％以上，ｓＰＳ的分子量Ｍｖ达到４．１５×１０５～２．４６×１０５范围，熔融温度高达５４３Ｋ．
CpTiCl3 / MAO, Cp * TiCl3 / MAO, Cp * Ti (OCH2CHCH2) 3 / MAO and Cp * Ti (OMe) 3 / MAO were synthesized. The results showed that [Cp * Ti (OCH2CHCH2) 3] / methylaluminoxane (MAO) had higher thermal stability and syndiotactic polymerization of styrene at 333 ~ 363K had the highest catalytic activity. The polymerization product The concentration of insoluble syndiotactic polystyrene (sPS) accounted for more than 98% of the total polymerization product, the molecular weight of sPS reached 4.15 × 105 ~ 2.46 × 105, and the melting temperature reached 543K.
