PROCESS FOR PREPARING CATALYTIC SYSTEM COMPONENT FOR POLYMERIZATION OF α-OLEFINS Russian patent published in 1995 - IPC

FIELD: processes for the preparation of ac catalytic system component for the polymerization of a-olefins. SUBSTANCE: the process comprises reducing titanium tetrachloride in the presence of a magnesium compound which is magnesium chloride. Titanium tetrachloride is reduced b y electrolysis on a cathode made of a material having a high hydrogen in a methanol solution. The latter contains (wt): 0.0056- 0.06 titanium tetrachloride and 0.56-0.87 MgCl₂. The process makes it possible to replace hydrocarbon solvents by readily available methanol and to employ electrochemical reduction instead of reduction with an organomagnesium compound which is difficult to obtain. EFFECT: simpler technology for the preparation of a component. 1 tbl
