| titleOfInvention | Method for producing propylene-ethylene block copolymer |
| abstract | (57) [Summary] [Structure] Using a trivalent or tetravalent titanium halide compound, and a solid catalyst component containing magnesium halide, a catalyst composed of an alkylaluminum compound and an electron donating compound, at least two reactors are provided. In the connected polymerization system, propylene alone or copolymerization of propylene and other olefin is first carried out, and then propylene and ethylene are polymerized to continuously produce a propylene-ethylene block copolymer. Propylene homopolymerization slurry obtained by polymerizing more than 20000 g / g solid catalyst component or copolymerization slurry of propylene and 6% by weight or less of other olefin is transferred to a reactor in which ether or ester is present to obtain ethylene and propylene. Propylene-ethylene characterized by polymerizing The process of lock copolymer. [Effect] Good quality balance of impact resistance, rigidity, processability, etc., and high productivity of propylene-ethylene block copolymer with high commercial value that does not produce fish eyes when forming a film or sheet. A method can be provided. |
