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。
The C70 / PS copolymer was characterized by SEC / RI / RALLS / DV triple detection. The problem that can not be explained by traditional SEC / RI is solved, and the general structure of C70 - PS copolymer is proposed. The results show that the C70 - PS copolymer / THF system does not meet the universal calibration.
