    摘要： An ethylene copolymerization catalyst is prepared by impregnating a porous support, such as silica, with an organomagnesium compound such as a magnesium alkyl and contacting the magnesium-containing support with a silane compound which is free of hydroxyl groups, such as a tetraalkyl orthosilicate, e.g. tetraethyl orthosilicate (TEOS). A transition metal component such as titanium tetrachloride is then incorporated into the support in a specific ratio to the magnesium and silane components. Activation of this catalyst precursor with a trialkylaluminum compound results in a catalyst which is effective for the production of ethylene copolymers.

    摘要： A polymer supported catalyst comprises Ziegler-Natta catalysts immobilized on a magnesium-modified polymer support. The catalyst support is prepared by (1) dissolving a carboxyl group-containing polymer in a solvent and precipitating the polymer in a polar non-solvent, (2) wet-grinding the precipitated polymer, and (3) mixing the ground polymer with an organomagnesium compound or a complex of an organomagnesium compound and an organoaluminum compound to give a magnesium-modified polymer support. Optionally, the resulting magnesium-modified support is treated with a halogen-containing silicon compound. The catalysts may be loaded onto the support by reacting the magnesium-modified support with a transition metal compound to form a catalyst constituent, and then combining the catalyst constituent with an appropriate organo-metallic compound. The supported catalyst is highly active and suitable for the polymerization and copolymerization of olefins without substantial contamination of the resulting products with chlorine or metal ions, as is the case with conventional MgCl.sub.2 -supported catalysts.
