| titleOfInvention | Process for the preparation of aromatic copolyesters |
| abstract | Process for obtaining alkyllaromatic copolyesters, characterized in that a diester of a dihydroxyaromatic compound and an aliphatic diacid of general formula HOOC (CH 2 ) n COOH with 3 are reacted successively at a temperature below 250 ° C. ≤ n ≤ 10 with a molar ratio of the diester to the diacid of between 1.5 and 4 until a rate of progress of the reaction greater than or equal to 85%, then, at temperature greater than 250 ° C., an aromatic dicarboxylic acid and / or cycloaliphatic and that the product obtained is polycondensed under reduced pressure for a duration of less than or equal to 1 h 30.n n n This process makes it possible to obtain copolyesters which can be transformed into wires, films, molded objects in the molten state. |
