ABSTRACT:
Polyether polymers are prepared from 4,4"-dihydroxy-m-terphenyls, especially the unsubstituted dihydroxyterphenyl, by reaction under alkaline conditions with bis(4-halophenyl) sulfones, 4,4'-dihalobenzophenones or gem-dihaloalkanes. Both homopolymers and copolymers with other dihydroxyaromatic compounds, particularly bisphenol A, may be prepared. They have glass transition temperatures higher than those of the corresponding bisphenol A-derived polymers.
