METHOD OF SYNTHESIS OF POLYMER OR ETHYLENE COPOLYMER Russian patent published in 1997 - IPC

Abstract RU 2097388 C1

FIELD: chemistry of polymers. SUBSTANCE: method involves gas-phase (co)polymerization of ethylene in the presence of chloroform and hydrogen. Catalytic system consists of alkylaluminium and catalyst obtained by interaction of a carrier - refractory hydroxyl-containing groups oxide - with dialkylmagnesium or its mixture with trialkylaluminium and, at least, one compound of tetravalent titanium. Products were used in plastic industry. EFFECT: improved method of synthesis. 6 cl, 1 dwg
