| titleOfInvention | The method that cyclic olefine copolymer is prepared using double activity center's composite catalyst |
| abstract | The invention discloses the method that a kind of use double activity center composite catalyst prepares cyclic olefine copolymer, comprise the following steps：Inert organic solvents, cycloolefin and ethene are separately added into reactor, are 1~50bar by the pressure adjusted to reactor punching press ethene in reactor；Then chain-transferring agent, double activity center composite catalyst are added and carries out solution polymerization, temperature be 40~1000 DEG C, pressure be to carry out polymerisation under the conditions of 1~50bar, polymerization reaction time is 15 minutes~10 hours.The present invention is both avoided using non-metallocene single active site catalyst because of the too high shortcoming for easily causing gel of the molecular weight of copolymer of gained, the cyclic olefine copolymer molecular weight distribution relative narrower obtained using metallocene catalysis system is solved again, the problem of machinability is poor. |
