Abstract

Solid catalytic components for the synthesis of high purity ethylene-propylene elastomer copolymers obtained by contacting an organometallic aluminium compound I diluted in aliphatic hydrocarbons with a liquid II prepared by: a) dissolving an anhydrous magnesium halide in a mixture of halohydrocarbons in the presence of an aluminium trihalide, b) treating with a tetravalent titanium compound of general formula Ti(OR)4-n X n, where R is an aliphatic, cycloaliphatic or aromatic hydrocarbon radical containing from 1 to 20 carbon atoms, X is a halogen atom and n is a whole number between 0 and 4. Liquid II is characterised by a molar Mg/Ti ratio of between 1 and 5, an Al/Mg molar ratio of between 1 and 5 and a molar ratio between Al and chlorine in the mixture of halohydrocarbons which is not less than 0.1.
