醇镁加合物载体在Ziegler-Natta催化剂中的应用进展OA北大核心CSTPCD

Ziegler-Natta(Z-N)catalyst based on alcohol magnesium chloride adduct support has the characteristics of excellent particle morphology and high activity.The property of alcohol magnesium chloride adduct support has a significant impact on the comprehensive performances of catalyst and polymer,which is currently a research priority in the field of polyolefin.This paper introduces the development history of magnesium chloride support and the preparation methods of alcohol magnesium chloride adduct support,analyses the effects of different alcohol magnesium ratios and alcohol categories on the structure of the support,and reviews the application status of alcohol magnesium chloride adduct support in Z-N catalyst.In addition,the future development of alcohol magnesium chloride adduct support for olefin polymerization is prospected.
