| titleOfInvention | A solid catalyst for propylene-based block copolymerization and a method for preparation of block copolymer |
| abstract | The present invention relates to a method for producing a solid catalyst for polypropylene production, and a method for producing a solid catalyst comprising a carrier produced through the reaction of dialkoxymagnesium with a metal halide, a titanium halide, two types of non-aromatic organic electron donors, etc. To provide a method for producing a propylene-based block copolymer through the copolymerization of the used propylene-alpha olefin. In particular, the organic electron donor used in the present invention is a mixture of two non-aromatic internal electron donors, and a block copolymer with a high rubber content is obtained through copolymerization with alpha olefin using the solid catalyst system presented in the present invention. can be manufactured. |
