| titleOfInvention | Method for producing propylene / olefin copolymer |
| abstract | (57) [PROBLEMS] To carry out a propylene / olefin copolymer using a metallocene catalyst system, to remove polymerization inhibitors in propylene and olefin by a simple method, and to obtain propylene with high polymerization activity. And a method for producing an olefin copolymer. In a metallocene catalyst system, propylene and an olefin treated by sequentially performing an activated alumina treatment and a molecular sieve treatment or a molecular sieve treatment, an activated alumina treatment and a molecular sieve treatment are used. The propylene and the olefin are copolymerized to form a propylene / olefin copolymer having an olefin content of 50% by weight or less. Activated alumina treatment and molecular sieve treatment or molecular The propylene and the olefin are copolymerized in the presence of a metallocene catalyst system using propylene and an olefin that have been sequentially subjected to a sieve treatment, an activated alumina treatment, and a molecular sieve treatment to obtain an olefin content. Is a propylene / olefin copolymer of 50% by weight or less. |
