The acid chloride of 1,4-bis-p-carboxphenyl-1,3-butadience and isophsthaloyl chloride were polymerized with 4,4-diphenoxy-diphenyl sulfone and diphenyl ether in a Friedel-Crafts type polymerization. The resulting polymers contained 5-20 mole of butadiene units and were insoluble in all solvents. Author
