| titleOfInvention | Manufacturing method of polyamide resin |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing a polyamide resin via a polyester resin, and to suppress or prevent the gelling / decomposition of a useful high molecular weight polyamide resin, To provide a process that can be produced in high yield. SOLUTION: For a linear polyester resin having a limiting viscosity of 0.2 dl / g or more comprising a dicarboxylic acid component and a divalent OH component, at least one diamine compound is selected from aprotic solvents. When a polyamide resin is produced by reacting in a reaction medium composed of various kinds of solvents and substituting the divalent OH component in the linear polyester resin with the diamine compound, At least one of a carboxylic acid activator and an inorganic salt was present in such a reaction system. |
