小角激光散射法研究聚苯基喹噁啉在稀溶液中的缔合现象

Association of Polyphenylquinoxaline in Dilute Solutions Studied by Low Angle Laser Light Scattering

聚[2,2′－（1，4－苯撑）－6，6′－双（3－苯基喹恶啉）]（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道，但是有关其溶液性质和分子形态的研究还甚少，我们用小解激光散射法研究了PPQ的稀溶液性质。本文报道PPQ在溶液中的缔合现象。

The association phenomena of poly [2, 2'-(1,4-phenylene)-6, 6'-bis(3-phenyl. quinoxaline)] (PPQ) in dilute solutions were observed from the concentration dependence of Kc/R_(e→0) in low angle lasor light soattering measurements. Depolarized light scattering technique was also performed to investigate the anisotropic nature of PPQ.
