Abstract

The data article refers to the paper "Synthesis of High-Vinyl Isoprene and Styrene Triblock Copolymers via Anionic Polymerization with Difunctional BuLi Initiator" [1]. Data presented here include the number average molecular weight ( ), the weight average molecular weight ( ), and polydispersity index (PDI) ( / ) of the triblock copolymers poly(styrene)poly(isoprene)poly(styrene) (PSPIPS, SIS) and poly(isoprene)poly(styrene)poly(isoprene) (PIPSPI, ISI). of SIS and ISI were in the range of 208,000 to 274,000 (g/mol) and PDI of SIS and ISI are located at 1.18 to 1.2, respectively. The triblock copolymers were further identified with 2D HSQC NMR spectrum. Different vinyl content (1,2- and 3,4-addition units) of polyisoprene domains were characterized in the data.

摘要

数据文章引用了论文《通过双官能丁基锂引发剂的阴离子聚合合成高乙烯基异戊二烯和苯乙烯三嵌段共聚物》[1]。此处给出的数据包括三嵌段共聚物聚（苯乙烯）-聚（异戊二烯）-聚（苯乙烯）（PSPIPS，SIS）和聚（异戊二烯）-聚（苯乙烯）-聚（异戊二烯）（PIPSPI，ISI）的数均分子量（）、重均分子量（）和多分散指数（PDI）（ / ）。SIS和ISI的在208,000至274,000（g/mol）范围内，SIS和ISI的PDI分别位于1.18至1.2。通过二维HSQC NMR光谱对三嵌段共聚物进行了进一步鉴定。数据中对聚异戊二烯链段不同的乙烯基含量（1,2-和3,4-加成单元）进行了表征。
