FIELD: chemistry.
SUBSTANCE: present invention relates to copolyhydroxyesters based on 3,3'5,5'-tetramethyl-4,4'-dioxy-diphenylsulphone and 4,4'-dioxy-diphenylsulphone, which can be used as film materials. Said copolyhydroxyesters are compounds of formula: 
, where n = 48–56.
EFFECT: obtained copolyhydroxyesters of said structure have improved values of glass transition temperature, fire resistance, heat resistance and mechanical properties, good solubility in dioxane, chlorinated organic solvents, N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone, have film-forming properties.
