FIELD: chemistry.
SUBSTANCE: invention relates to a process for the preparation of aromatic copolyarylene ether sulfones of the following formulas, which can be used as thermally and heat-resistant structural polymeric materials. Method for the preparation of aromatic copolyarylene ether sulfones is to conduct high-temperature polycondensation of 4,4'-dichlorodiphenylsulfone and diphenols, which are introduced stepwise. Molar ratio of diphenols is from 0.1 to 0.9 and from 0.9 to 0.1. Reaction mixture was diluted with N,N-dimethylacetamide distilled off during the synthesis.
