| titleOfInvention | The method of obtaining polyesters and polyester resins with a carbazole ring |
| abstract | Method for obtaining unsaturated polyesters and polyester resins with a carbazole ring of general formula 1, in which x and y denote the number of units derived from propane-1,2-diol and 3- (9-carbazolyl) propane-1,2-diol-, where x + y = 1 and x and y are not less than zero, by polycondensation of the starting components, among which there are alkylene glycols and maleic and fumaric anhydrides, is characterized by the fact that in the polycondensation reaction of diethylene glycol and propane-1,2-diol with phthalic anhydride and maleic anhydride, 3- (9-carbazolyl) propane-1,2-diol is used in place of at least part of propane-1,2-diol, esterified at 170 to 220 ° C under an inert gas cushion, with azeotropic removal of water condensing, to an acid value below 50 mg KOH / g, and then the polyester obtained is cooled to a temperature below 100 ° C and dissolved in the crosslinking corneoner. |
