    摘要: A branched, high molecular-weight polyaryl-ether sulphone which is the reaction product of approximately equimolar amounts of an aromatic dialkali metal bishydroxylate and a bis-(halogen-aryl) compound, whose aryl nuclei are linked by sulphonyl groups, and about 0.01 to about 2 mol %, based on the bishydroxylate or bis-(4-halogenaryl) compound, of an aromatic compound having at least three aromatically linked alkali metal hydroxylate substitutents and/or of a halogenaryl compound having at least three aryl-linked halogen substituents and which is capable of substitution under the reaction conditions of polyaryl-ether sulphone manufacture.
