Process for production of polyamide |
| abstract |
An economical batchwise production method of polyamide with good quality by the polycondensation in which a diamine component including 70 mol % or more of a xylylenediamine which includes 20 mol % or more of p-xylylenediamine is added to a dicarboxylic acid component in a batchwise reaction tank equipped with a partial condenser. The diamine component is added while maintaining the whole reaction system in fluid state under pressure. The pressure is reduced during the time that the molar ratio is within a specific range while continuing the addition. |
