摘要: 用SEC/RI/RALLS/DV 三检测技术表征了C70/PS 共聚物。解决了用传统SEC/RI不能解释的现象,提出了C70 - PS共聚物的大致结构。结果表明C70 - PS共聚物/THF体系不符合普适标定。Abstract: C 70 -PS copolymer was characterized via SEC/RI/RALLS/DV tri-detector technique. The problems existed in conventional SEC characterization for C 70 -PS were solved. The highly branching structure of C 70 -PS was proposed. The results show that
