摘　　要：通过1H{13C}NM R、1H-1H COSY、13C-1H HSQC和13C-1H HM BC一维和二维核磁实验分析氢化苯乙烯/异戊二烯共聚物(HS IP)的微观结构。一维核磁实验1H{13C}NM R提供了HS IP的基本结构信息;通过1H-1H COSY实验确定同核H之间的耦合关系,明确了H的化学环境;13C-1H HSQC确定异核13C-1H的单键相关性,明确了直接相连接的C-H化学位移;13C-1H HM BC确定异核碳氢原子的远程相关性(2—3键),验证化学位移归属的正确性和微结构的存在性。The microstructure of hydrogenated styrene-isoprene copolymer（HSIP） was analyzed by 1H{13C}NMR,1H-1H COSY,13C-1H HSQC（heteronuclear single quantum correlation） and 13C-1H HMBC（heteronuclear multiple bond correlation） one-dimensional and two-dimensional.The basic structure information of HSIP was provided by one-dimensional 1H{13C}NMR,and the chemical environment of 1H was definited through confirming the coupling relationship between homonuclear 1H by 1H-1H COSY experiment,and the single bond correlation of hererocaryosis 1H-13C was identified by 13C-1H HSQC,and the chemical shift of directly connected C—H was confirmed,and the remote correlation of carbon and hydrogen atoms in hererocaryosis was confirmed by 13C-1H HMBC（2—3 bonds）,and the correctness of the vested chemical shift and existence of microstructure were verified.
