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。
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 the universal calibration does not fit in with C 70 -PS/THF system.
