摘要
用^(13)C—NMR方法研究了端羧基丁二烯-丙烯腈液体共聚物的序列分布和微观结构。结果指出,丙烯腈单体主要以BAB三元组形式存在,并给出了定量数据。
Sequence distribution and microstructure in terminal carboxyl liquid butadiene-acrylonitrile copolymers were studied by ^(18)C-NMR method to confirm the acrylonitrile residues mainly in BAB triads and we give quantitative data concerning their triads composition.
