Abstract
Thermoplastic copolymers are formed by the interaction of a 4-mercaptophenol and a dihalo-substituted aromatic sulfone of the structure X--phenylene-SO.sub.2 2-phenylene) .sub.y X, wherein y is 1 or 2. The latter are typified by 4,4'-dichlorodiphenyl sulfone and 4,4'-bis(4-chlorophenylsulfonyl)biphenyl. The mercoptophenol may have one or two lower alkyl groups ortho to the hydroxyl. The polymers are characterized by high glass transition temperatures and high impact strength.
