IPC: C08F4/64
Filed: 1983-10-06
Abstract: PURPOSE:To produce the titled catalyst free of coarse particles in good efficiency, by classifying a specified copulverizate, allowing the fine particles as such to support a titanium halide and, after adding a halohydrocarbon and copulverizing the mixture, allowing the product to support a titanium halide.
