| titleOfInvention | The preparation method of the vinylaromatic hydrocarbon conjugated diene block copolymer for the utilization coupled reaction that ion stability is improved |
| abstract | The preparation method of the vinylaromatic hydrocarbon conjugated diene block copolymer for the utilization coupled reaction being improved the present invention relates to ion stability.The present invention provides a kind of preparation method of vinylaromatic hydrocarbon conjugated diene block copolymer, and it includes：It polymerize vinyl aromatic hydrocarbon monomer by organo-lithium compound polymerization initiator in hydrocarbon solvent, so that the step of forming the first mixed solution comprising vinylaromatic hydrocarbon block (a)；And conjugate diene monomer is added in the first mixed solution of step (a), and conjugated diene block is formed in vinylaromatic hydrocarbon block end, so that the step of forming the second mixed solution comprising the block conjugated diene block of vinylaromatic hydrocarbon (b)；Wherein, the preparation method of the vinylaromatic hydrocarbon conjugated diene block copolymer is characterised by, comprising：By lewis acid before the polymerization of the vinyl aromatic hydrocarbon monomer of step (a) triggers, it is added to the step (c) in the first mixed solution in polymerization or when polymerization is completed. |
