Abstract
A solid catalyst for olefin polymerization which is obtained by the catalytic treatment of a titanium trichloride composition with a mixture of a halogenated hydrocarbon and an ether, the composition being produced by subjecting a solid reduction product, which is obtained by reduction of titanium tetrachloride with an organo-aluminum compound, to heat treatment or to catalytic treatment with a specific organo-aluminum compound, aluminum halide, an ether and the like. In the polymerization of an olefin, combined catalyst systems of this solid catalyst and organo-aluminum compounds as activators can be used for efficient production of olefin polymers having a high crystallinity.
