Claims
- 1. An amorphous thermoplastic terpolymer consisting essentially of the following repeating units which are connected by ether linkages: ##STR12## said terpolymer is produced by the reaction of dichlorodiphenyl sulfone and a mixture of hydroquinone and dihydroxydiphenyl sulfone.
- 2. A terpolymer as defined in claim 1, wherein the ratio of unit (I) to unit (II) is in the range of from about 70:30 to 85:15.
- 3. The terpolymer as defined in claim 1 produced by reacting dichlorodiphenyl sulfone with at least a one to one mole ratio of dihydroxydiphenyl sulfone to hydroquinone.
- 4. The terpolymer as defined in claim 1 produced by reacting dichlorodiphenyl sulfone with at least a one to three mole ratio of dihydroxydiphenyl sulfone to hydroquinone.
- 5. The terpolymer as defined in claim 1 produced by reacting dichlorophenyl sulfone with at least a three to one mole ratio of dihydroxydiphenyl sulfone to hydroquinone.
- 6. A terpolymer as defined in claim 1 which is blended with one or more compatible thermoplastic polymers selected from the group consisting of polyarylates, poly(aryl ethers), polyetherimides, polyesters, aromatic polycarbonates, polyurethanes, and polyhydroxyethers.
