Abstract:
Solid Lewis adducts comprising MgCl2, a Lewis base (LB) belonging to ethers, esters, ketones, silanes or amines and an alcohol ROH, in which R is a C1-C15 hydrocarbon group optionally substituted with heteroatoms containing groups, which compounds are in molar ratios to each other defined by the following formula MgCl2(ROH)m(LB)n in which m ranges from 0.05 to 6, n ranges from 0.08 to 6. The solid Lewis adducts herein can be used to prepare catalysts having good morphological stability, and high polymerization activity.
