✦ Synopsis

Blends of the polyhydroxyether of bisphenol-A (Phenoxy) and a series of ethylene terephthalate (ET)-caprolactone (CL) random copolyesters (TCL) having different ET contents were examined mainly by differential scanning calorimeter (DSC). A miscibility limit specified by the ET content was obtained and estimated to be about 90 wt%. When the ET content is less than this limit, the Phenoxy and copolyesters aTe miscible with each other. A relatively stronger specific intermolecular interaction between Phenoxy and copolyester was detected by Fourier Transform infra-red (FTIR) spectroscopy, and it may be an important factor which affects the miscibility in these blends. Based on the miscibility behaviour of PhenoxyjTCL copolyester blends, the factors which affect the miscibility of Phenoxy with polyester was discussed.
