| titleOfInvention | A kind of preparation method of halogen polymer |
| abstract | The invention discloses a kind of preparation methods of halogenation monoolefine-conjugated diene copolymer, it is included under the conditions of cationic polymerization, conjugated diene shown in monoolefine shown in Formula II and formula III is contacted with each component in initiator system in the in the mixed solvent of alkane and halogenated alkane, the halogenated alkane in solution obtained with alkane metathesis polymerizable, after deviating from unreacted monomer simultaneously, it is contacted with halogen-containing compound, carry out halogenation, the initiator system contains the compound for being capable of providing proton, lewis acid and activator, the activator is selected from -2 compound represented of -1 compound represented of Formulas I and Formulas I.This method can significantly improve polymerization efficiency, obtain higher polymer yield；The polymer with higher molecular weight can also be obtained；It is omitted simultaneously and process is redissolved using polymer necessary to slurry polymerization process, simplify production technology. |
