可溶性茂钛催化剂对乙烯的聚合及表征

Soluble Titanocene Catalyst for Ethylene Polymerization and its Characterization

研究了不同的茂钛催化剂与甲基铝氧烷 ( MAO)组成的催化体系对乙烯的聚合 ,发现钛的配体会大大影响聚合活性。从聚乙烯的透射电镜照片及偏光显微镜的照片 ,进一步证实聚乙烯的结晶性很好 。

The polymerization of ethylene with various titanocene/methylaluminoxane (MAO) catalytic systems was studied. Results showed that the ligand of titanium affects the catalytic activity seriously. Crystallinity of polyethene as shown by spherulite observation of TEM and PM microroph was very good.
