SPHERICAL CATALYST COMPONENT FOR ETHYLENE POLYMERIZATION, CATALYST FOR ETHYLENE POLYMERIZATION, METHOD OF ETHYLENE POLYMERIZATION, ETHYLENE AND PROPYLENE COPOLYMERS Russian patent published in 1998 - IPC

FIELD: chemical technology. SUBSTANCE: invention relates to the spherical catalysts for olefin polymerization containing titanium compound applied on magnesium dichalide and containing at least a single bond titanium-halogen and if necessary the electron-donor compound. Spherical components of catalyst exhibit porosity value above 1 cm³/g and pore distribution, for example, 30% of total pore size have average radius above 10 000 . Invention describes also the catalyst of ethylene polymerization, method of ethylene polymerization using the proposed catalyst and copolymers of ethylene and propylene synthesized. EFFECT: improved method of synthesis. 20 cl, 6 ex
