Abstract
FIELD: production of elastomer ethylene-propylene copolymers. SUBSTANCE: proposed solid component contains titanium compound being applied on solid carrier which mainly comprises MgCl. Said component is prepared by interaction of solution (I) which mainly contains organometallic compound of aluminium (which is dissolved in aliphatic hydrocarbons) with solution (II). Mentioned above solution (II) contains anhydrous magnesium halide in mixture of solvent and compound of tetravalent titanium having common formula Ti(OR)X. Said mixture of solvents is chosen of halogen-containing hydrocarbon and aromatic hydrocarbons and corresponding mixtures. EFFECT: improves quality of desired product.
