高刚性聚丙烯催化剂制备影响条件的研究

聚丙烯催化剂是工业生产中最常见的催化剂,为了提高聚丙烯的高刚性高等规度,对催化剂做了一系列的改进。采用二酯类给电子体,得出温度为-22℃,搅拌速度350r/min、反应时间在3h时制备的催化剂能达到制备高刚性聚丙烯的要求。

Study on Two Ester Catalyst for Electron Donor Polypropylene

Polypropylene catalyst is the most common type of catalyst in the industrial production, in order to improve the high rigidity higher normality of polypropylene, we to the catalyst made a series of improvements, this experiment adopts two esters to electronic, it is concluded that the temperature was minus22 ℃, stirring speed of 350 r/min, reaction time on preparation of catalysts to the preparation of 3 h the requirements of high stiffness polypropylene.
