摘要: 用GPC-连续型粘度计-小角激光光散射光度计三联用装置研究了GPC普适标定对长链支化聚氯乙烯试样的适用性问题。结果证实:支化度因子在0.4以上的所有支化聚氯乙烯级份和线形聚氯乙烯级份一样,普适标定均是适用的。

Abstract: The applicability of universal calibration to a long branched chain of polyvinylchloride is researched immediately by the apparatus of GPCcombined with a continuous viscometer and a low angle laser light scattering photometer.Results show that universal calibrations are all applicable to fractions of all branched polyvinylchloride whose branched parameter g'(= [η]b/[η]l) is more than 0.4 and the fractions of linear polyvinylchloride.
