A chemical analog of poly(vinyl phenol) mixes exothermically with analogs of polyacetal and poly(ethylene oxide), suggesting miscibility in the case of blends of poly(vinyl phenol) with polyacetal and with poly(ethylene oxide). The interaction parameter corresponding to the poly(vinyl phenol) and the poly(ethylene oxide) analog mixtures agrees well with an interaction parameter reported for the polymer mixtures, which was based on the melting point depression of poly (ethylene oxide ) in blends with poly (vinyl phenol). FTi.r. spectroscopy indicates the presence of strong hydrogen bonding between phenol and ether groups in these analog mixtures. Application of the binary interaction model predicts that a rather wide range of styrene-vinyl phenol copolymers would exhibit miscibility with polyacetal.
