CATALYST FOR THE PREPARATION OF ELASTOMERIC ETHYLENE-PROPYLENE COPOLYMERS

摘要

Solid component of a catalyst for the synthesis of elastomeric Ethylene-Propylene copolymers typically amorphous, basically consisting of a Titanium compound supported on a solid component mainly consisting of MgCl2, prepared by a process which comprises putting a solution (I), basically consisting of an organometallic compound of Aluminium diluted with aliphatic hydrocarbons, in contact with a solution (II) containing - an anhydrous Magnesium halide in a composition of solvents selected from halohydrocarbons and aromatic hydrocarbons and relative mixtures, in the presence of an Aluminium trihalide; - a tetravalent Titanium compound having general formula Ti(OR)4-nXn.
