CATALYST FOR PREPARING POLYMERIZATION-FILLED POLYETHYLENE Russian patent published in 1997 - IPC

Abstract SU 1396331 A1

FIELD: catalysts for olefin polymerization processes. SUBSTANCE: catalyst is supplemented by organomagnesium compound with formula Mg(C4H9)2•0,12Al(C2H5)2 or Mg(C4H9)(C2H5). Catalyst contains (in mmol/g): powder mineral filler (kaolin) - AlCl(C2H5)2, 0.05-0.4; titanium tetrachloride, 0.4-1.2; and organomagnesium compound, 0.16-0.4. Catalyst provides increasing productivity to 42 polyethylene/g Ti h atm and allows controlling molecular weight of polymer by adding hydrogen and also filler (up to 50 wt %) into polymerization mass. EFFECT: increased catalyst activity. 1 tbl
