聚[2,2'-(1,4-苯撑)-6,6'-双(3-苯基喹 啉)](PPQ)是一种耐高温材料, 其合成方法, 机械性能及应用方面的研究已有很多报导, 但是有关其溶液性质和分子形态的研究还甚少。本文用小角激光散射法研究了PPQ的稀溶液性质, 并报导了PPQ在溶液中的缔合现象。

关键词: 苯 P, 缔合, 性质, 小角激光光散射法, 喹啉 P, 稀溶液

The association phenomena of poly[2,2'-(1,4-phenylene)-6,6'-bis(3-phenylquinoxaline)] (I) in dilute solns. were observed from the concentration dependence of Kc/Rq? in small-angle laser light scattering measurements. Depolarized light scattering technique was also performed to investigate the anisotropic nature of I.

Key words: BENZENE P, ASSOCIATION, PROPERTIES, SMALL ANGLE LASER SCATTERING, QUINOXALINE P, DILUTE SOLUTION
