异戊二烯－乙烯基芳香烃共聚物及其合成方法;COPOLYMER OF ISOPRENE AND VINYL AROMATIC HYDROCARBON AND THE SYNTHESIS METHOD THEREOF

摘要

本发明提供一种异戊二烯-乙烯基芳香烃共聚物，其包括异戊二烯结构单元以及乙烯基芳香烃结构单元。异戊二烯结构单元具有由式(1)和式(2)表示的乙烯基结构单元。由式(1)和式(2)表示的乙烯基结构单元的数量为异戊二烯-乙烯基芳香烃共聚物中异戊二烯结构单元的总数量的X%。由两个相连或大于两个相连的乙烯基芳香烃结构单元组成的嵌段中的乙烯基芳香烃结构单元的数量，占异戊二烯-乙烯基芳香烃共聚物中乙烯基芳香烃结构单元的总数量的Y%，其中Y/X=0.09~0.41。;A copolymer of isoprene and vinyl aromatic hydrocarbon including an isoprene structure unit and a vinyl aromatic hydrocarbon structure unit is provided. The isoprene structure unit has a vinyl structure unit represented by formulae (1) and (2). The number of the vinyl structure unit represented by formulae (1) and (2) is X% of the total number of the isoprene structure unit. The number of the vinyl aromatic hydrocarbon structure unit in at least one block consisting of two or more than two connected vinyl aromatic hydrocarbon structure units is Y% of the total number of the vinyl aromatic hydrocarbon structure unit. Y/X=0.09~0.41.
