POLYAROMATIC ETHER-KETONE-SULFONES CONTAINING 1,3-BUTADIENE UNITS

In the reported experiments, the acid chloride of 1,4-bis-p-carboxyphenyl-1,3-butadiene (XI) and isophthaloyl chloride (XIV) were polymerized with 4,4 prime -diphenoxy-diphenyl sulfone (XII) and diphenyl ether (XIII) in a Friedel-Crafts type of polymerization. The polymers obtained, which contained 5-20 mole % of butadiene units, were insoluble in all solvents. The polyamides prepared from the acid chloride of 1,4-bis-p-carboxylphenyl-1,3-butadiene (XI) and aromatic diamines were also insoluble in all solvents.
