Lewis Adduct comprising a Magnesium dichloride, Alcohol and other specific amounts of Lewis base Catalyst and method of olefin polymerization

摘要

Lewis adducts Solid containing MgCl2, a Lewis base (lb) belongs to ethers, esters, ketones, amines and a Silane or alcohol Roh, where r is an optionally substituted Hydrocarbon Group C1 - 15 of groups containing heteroatoms, whose compounds are in molar ratios Among them are defined by the following formula (Roh) M MgCl2 (lb) n, where m varies between 0.05 and 6N varies between 0.08 and 6. These adducts can prepare Catalyst with good morphological stability and High polymerization activities.
