    摘要: A method of preparing a polymerization catalyst which involves impregnating a catalyst support with chromium oxide and a titanium complex formed by reacting a titanium alkoxide a compound selected from the group consisting of R''xSn(OH)m and R''''pB(OH)q in which R'' and R'''' are selected from the group consisting of alkyl, aryl, and cycloalkyl radicals and combinations thereof.

    摘要: A catalyst is formed by combining a support material with (1) a chromium-containing compound such as chromium trioxide and (2) at least one of a gallium-containing compound such as gallium isopropoxide, and a tin-containing compound such as tin isopropoxide, and then activating the catalyst by heating at a temperature of at least 1,700* F. Polymers such as polyethylene formed using the catalyst of this invention have a narrow molecular weight distribution.
