METHOD OF PREPARATION OF CATALYTIC SYSTEM COMPONENT FOR POLYMERIZATION OF ALPHA-OLEFINS Russian patent published in 1995 - IPC

Abstract SU 1503134 A1

FIELD: catalytic chemistry. SUBSTANCE: metallic magnesium is dissolved in methanol saturated with hydrogen chloride with subsequent addition of TiCl4 in the necessary relation to magnesium, then electrochemical reduction of TiCl4 to TiCl3 is accomplished. The test of activity of obtained catalytic system jointly with cocatalyst triethyl aluminium in reaction of polymerization of ethylene and propylene shows activity similar to the known one. EFFECT: simplified process and reduced time of preparation from 16 h to 5 to 10 min. 1 tbl
