| titleOfInvention | Method for producing propylene block copolymer |
| abstract | (57) 【Abstract】 PROBLEM TO BE SOLVED: A method of combining a bulk metalization method or a gas phase polymerization method with a catalyst system comprising a transition metal catalyst component in which a titanium halide is supported on magnesium halide and an organoaluminium compound is superior, The block copolymer thus obtained solves the problems of poor moldability and appearance of the molded product, and provides a method for efficiently producing polypropylene suitable for extrusion molding and blow molding. SOLUTION: A propylene is first polymerized and then propylene and ethylene are copolymerized by using a catalyst composed of a transition metal catalyst component in which a titanium halide is supported on magnesium halide, an organoaluminum compound and dicyclohexyldialkoxysilane. A block copolymer of propylene having a melt flow index of 10 g / 10 min or less measured at ° C is produced. |
