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.

Abstract: Aductos de Lewis sólidos que comprenden MgCl2, una base de Lewis (LB) que pertenece a éteres, ésteres, cetonas, silanos o aminas y un alcohol ROH, donde R es un grupo hidrocarburo C1-15 opcionalmente sustituido por grupos que contienen heteroátomos, cuyos compuestos están en relaciones molares entre sí definidas por la siguiente fórmula MgCl2(ROH)m(LB)n, donde m varía entre 0,05 y 6, n varía entre 0,08 y 6. Estos aductos permiten preparar catalizadores con una buena estabilidad morfológica y altas actividades de polimerización.

Abstract: A catalyst component for olefin (co)polymerization, and in particular for the preparation of LLDPE, comprising Mg, Ti, halogen and an electron donor compound (ED) belonging to ethers, esters, amines, ketones, or nitriles, characterized in that the molar ratio Mg/Ti is higher than 5, and the molar ratio ED/Ti is higher than 3.5. The said catalyst components display a homogeneous distribution of the comonomer in and among the copolymer chains.
