Polyhydroxyethers formed by reacting a diglycidyl ether of biphenol, such as diglycidyl ethers of bisphenol-A, and a dihydroxybiphenyl, such as dihydroxybiphenyl, tetramethyldihydroxybiphenyl, and tetrabromotetramethyldihydroxybiphenyl, exhibit high heat distortion temperatures. These compositions could find utility in extruded films, packaging and coatings.
