SPHERICAL COMPONENTS OF CATALYST OF OLEFIN POLYMERIZATION, CATALYST OF POLYMERIZATION, METHOD FOR POLYMERIZATION OF ETHYLENE COPOLYMERS Russian patent published in 1998 - IPC

FIELD: production of polymers having controlled structure. SUBSTANCE: spherical solid components of catalyst for olefin polymerization comprise titanium compound supported on magnesium dihalide in activated form. Titanium compound has at least one titanium halide bond and one OR group bound with titanium atoms, molar ratio OR/Ti is 0.5 or higher. Proposed solid components also may comprise electron donor compound. Porosity of proposed solid components is 0.35-0.7 cm³/g, at least 50 % of porosity is produced by pores having average radius more 800 . EFFECT: improved activity of catalyst. 27 cl
