| titleOfInvention | Method for continuous gas phase production of propylene-based block copolymer |
| abstract | <P>PROBLEM TO BE SOLVED: To provide a method for producing a propylenic block polymer having a high rigidity and a high impact strength, containing reduced fish eyes, reducing the production of bulky polymers and adhesive polymers, and free from stickiness in a good flowing state. <P>SOLUTION: This method for continuously producing the propylenic block copolymer in a gas phase is characterized by comprising a first process and a second process in the presence of a specific solid catalyst component in a horizontal reactor having a stirrer rotated on a horizontal shaft in the inner portion, wherein an electron-imparting compound is added to the first process or the second process. <P>COPYRIGHT: (C)2008,JPO&INPIT |
