| titleOfInvention | Method for producing polyesteramide elastomer |
| abstract | (57) [Summary] (Modified) [Purpose] To provide a method for efficiently producing a polyesteramide having excellent mechanical strength at room temperature and high temperature, moldability, chemical resistance and transparency. [Structure] Aliphatic dicarboxylic acid containing adipic acid as a main component, and aliphatic diol containing ethylene glycol, butylene glycol and neopentyl glycol as main components, 100 parts by weight of the polyester constituent component having a reduced viscosity of 1.8 to 7.0 (1 g / dL 98% sulfuric acid solution, 20 C.) 5 parts by weight or more and less than 25 parts by weight of polyamide is dissolved, and a polyol having 3 to 6 hydroxyl groups, a polycarboxylic acid having 3 to 4 carboxyl groups, and a hydroxyl group and a carboxyl group are dissolved therein. A branching agent of an oxy acid having a group number of 3 to 6 with 0.1 to 2.5 mol per 100 mol of the aliphatic dicarboxylic acid, and the esterification reaction of the polyester constituent component is 150 to 230. After carrying out at 0 ° C., the resulting clear homogeneous solution is concentrated under reduced pressure at 20 ° C. Polymerize at 0-260 ° C. |
