The present invention is directed to a copolymer of a monomer selected from the group consisting of 1,3-butadiene and isoprene, and a monomer of formula I
wherein R
1
is a covalent bond, phenylene, a linear or branched alkane diyl group containing 1 to 10 carbon atoms, or a combination of one or more phenylene groups and one or more linear or branched alkane diyl groups containing 1 to 10 carbon atoms; and R
2
is hydrogen or a linear or branched alkyl group containing 1 to 10 carbon atoms; and X is a sulfur atom or a structure of formula II or III, wherein when X is of formula III, the S atom of formula III is adjacent to the phenyl ring of formula I and the N atom of formula III is adjacent to R1.
本发明涉及一种共聚物,该共聚物由从1,3-丁二烯和异戊二烯中选择的单体以及式I的单体共聚而成,其中R1是共价键、苯基、含有1至10个碳原子的线性或支链烷基二基团,或一个或多个苯基和一个或多个含有1至10个碳原子的线性或支链烷基二基团的组合;R2是氢或含有1至10个碳原子的线性或支链烷基基团;X是硫原子或式II或III的结构,当X为式III时,式III的S原子与式I的苯环相邻,式III的N原子与R1相邻。
