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.

Ionic Elastomer Blends With Syndiotactic Polybutadiene
A neutralized sulfonated EPDM terpolymer is rendered amenable to adhesion utilizing typical foot sole primer/adhesive systems by incorporating into the sulfonated EPDM a syndiotactic 1,2-polybutadiene. The composition preferably includes process oils; inorganic fillers and preferential plasticizers for the neutralized sulfonated EPDM terpolymer.
