MAGNESIUM DICHLORIDE-ETHANOL ADDUCTS AND ATALYST COMPONENTS OBTAINED THEREFROM

摘要

Adducts are provided comprising MgCl2, ethanol and a Lewis base (LB), said compounds being present in molar ratios defined by the following formula MgC12.(EtOH)n(LB)p in which n is from 2 to 6 and p has values satisfying the following equation p/(n+p)<=0.1. The said adducts can be used as precursor in the preparation of high activity ZN catalysts.
