Abstract

1505994 Polymerisation catalyst BRITISH PETROLEUM CO Ltd 21 May 1975 [11 June 19741 25832/74 Heading B1E [Also in Division C3] An olefin polymerisation catalyst is prepared by (i) heating a support material comprising silica, alumina, thoria, zirconia or composites thereof, having chemisorbed surface hydroxyl groups, successively or simultaneously with a titanium compound and one or more compounds of metals selected from B, Cu, Mg, Al, Zr, Th, V, Cr, Mo, W, Mn, Fe, Co, Ni, Zn, Ga, Sn, Pb or La at a temperature of 150-1200‹C, and (ii) incorporating in the product under substantially anhydrous conditions a chromium compound and heating at 100-900‹C to activate the catalysts. The support may be reacted with the titanium and metal compound(s) in two or more steps with intermediate rehydroxylation of the support with a hydroxyl-containing compound, e.g. water or an alcohol. The examples relate to silica-supported compositions.
