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

FIELD: chemistry.

SUBSTANCE: copolymers can be used as heat-resistant construction materials. or , where n=1-20, m=1-100. The method for synthesis of said aromatic copolymers involves polycondensation of oligoformal based on diane or phenolphthalein with degree of polycondensation equal to 1-20 with diacyl chloride of terephthaloyl-di(p-oxybenzoatom) in 1,2-dichloroethane in the presence of triethylamine at 15-25°C for 1-1.5 hours.

EFFECT: wide range of polycondensation copolymers with good thermal properties.
