摘要:
A solid catalyst for polymerization of olefins prepared by treatment of a titanium trichloride composition with a mixture of (1) a halogen, an interhalogen compound or a halogenated hydrocarbon compound, and (2) an ether which, in combination with organoaluminum compounds as activators, can be used to polymerize olefins for the efficient production of highly crystalline olefin polymers.
