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
