AROMATIC COPOLYESTER-SULPHONE KETONES AND SYNTHESIS METHOD THEREOF Russian patent published in 2011 - IPC C07C69/90 C08G63/02 C08G63/127 C08G63/13 C08G63/133 C08G63/688 

FIELD: chemistry.

SUBSTANCE: invention relates to aromatic copolyester-sulphone ketones and synthesis method thereof. Aromatic copolyester-sulphone ketones can be used as heat resistant construction materials and are compounds of general formula: : or , where m is statistical distribution of structures on the macrochain m=1-100, a n=1, 5, 10, 20. The aromatic copolyester-sulphone ketones are obtained via polycondensation of oligosulphone-ketones based on diane or phenolphthalein with diacyl chlorides of terephthaloyl-di(p-oxybenzoic acid) in 1,2-dichloroethane in the presence of double excess triethylamine.

EFFECT: obtaining aromatic copolyester-sulphone ketone, having high thermal stability and heat resistance.
