Abstract
AbstractThe miscibility of poly(hydroxyether of bisphenol A) (phenoxy) with a series of poly(ethylene oxide‐co‐propylene oxide) (EPO) has been studied. It was found that the critical copolymer composition for achieving miscibility with phenoxy around 60°C is about 22 mol % ethylene oxide (EO). Some blends undergo phase separation at elevated temperatures, but there is no maximum in the miscibility window. The mean‐field approach has been used to describe this homopolymer/copolymer system. From the miscibility maps and the melting‐point depression of the crystallizable component in the blends, the binary interaction energy densities, Bij, have been calculated for all three pairs. The miscibility of phenoxy with EPO is considered to be caused mainly by the intermolecular hydrogen‐bonding interactions between the hydroxyl groups of phenoxy and the ether oxygens of the EO units in the copolymers, while the intramolecular repulsion between EO and propylene oxide units in the copolymers contributes relatively little to the miscibility. © 1993 John Wiley & Sons, Inc.
