Abstract
Solid component of a catalyst for the synthesis of predominantly amorphous ethylene-propylene elastomer copolymers, essentially comprising a titanium compound supported on a solid predominantly comprising MgCl2 prepared by a process which comprizes placing a solution I essentially comprising an organometallic compound of aluminium diluted with aliphatic hydrocarbons in contact with a solution II containing - an anhydrous magnesium halide in a mixture of liquids made up of halohydrocarbons and aromatic hydrocarbons in the presence of an aluminium trihalide, - a tetravalent titanium compound of general formula Ti(OR)4-nXn.
