摘要： 荧光光谱分析作为一种强有力的手段,为在更小的尺寸范围内研究共混体系相容性提供了可能.这类工作主要分3种类型:其一是以Morawatz和他的同事为代表的非发射能量转移法,利用处于不同分子链的生色基团在一定的空间距离内激发态能量互相转移,检测体系分子链间的接近程度,从而判断组分间相容性.

关键词: 共混物, 相容性, 荧光光谱, 激基复合物

Abstract: The fluorescence spectra of blends of ethylene terephthalate-caprolactone copoly-mer(TCL)with polyhydroxy ether of bisphenol-A(PH)are reported.A broad symmetricemission band without fine structure at about 450nm was observed.The peak is attributed tothe exciplex emission from chromophores in TCL and PH and is in relation with the miscibili-ty behaviour of the blends.

Key words: blend, miscibility, fluorescence spectrum, exciplex
