STUDY OF THE MOLECULAR WEIGHT OF HDPE CONTROLLED BY DIISOBUTYLZINC
二异丁基锌控制高密度聚乙烯分子量的研究

In the polymerization of ethylene by TiCl4-MgCl,-AlCla/Al(i-Bu)s-Zn(i-Bu)2 catalyst system, the influences of Zn(i-Bu)2 on the catalytic activity and the molecular weight of polyethylene has been studied. It is concluded that the molecular weight of polyethylene may be effectively controlled by Zn(i-Bu)2 alt proper conditions of polymerization.
