CATALIZZATORE PER LA POLIMERIZZAZIONE DI OLEFINE. |
摘要 |
A catalyst comprising (A) a solid catalyst component obtained by reacting a titanium compound having a hydrocarbyloxy group with an organoaluminum compound in the presence of an ether to give a liquid material or to give a solid titanium component (a) which is solubilized by addition of a tetravalent titanium halide with or without an ether without separation or after separation from the reaction mixture, and heat treating the liquid material at a temperature of 70 DEG to 180 DEG C. with or without addition of a tetravalent titanium halide, and (B) an organoaluminum compound is effective for polymerization or copolymerization of olefins with high stereoregularity and has high polymerization activity. |
