FIELD: chemistry.
SUBSTANCE: present invention relates to copolyhydroxyethers based on 4,4'-dioxyphthalophenone and 4,4'-dioxy-3,3'5,5'-tetrachlorophthalophenone, which can be used as film materials with improved glass transition temperature, fire resistance, heat resistance and mechanical properties. Said copolyhydroxyesters are compounds of formula:
, where n = 42÷50.
EFFECT: obtained copolyhydroxyesthers 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.
