摘要:
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 MgC12(ROM) m(LB)n in which m ranges from 0.05 to 6, n ranges from 0.08 to 6. These adducts allow to prepare catalysts having a good morphological stability and high polymerization activities.
