| titleOfInvention | Method of preparing polyamide |
| abstract | The process for producing a polyamide of the present invention is characterized in that a dicarboxylic acid component containing 5 to 40 mol% of terephthalic acid and a diamine containing 70 to 100 mol% of xylylenediamine having a content of para-xylylenediamine of 50 to 100 mol% Subjecting the component to a polycondensation reaction at a reaction temperature of 200 ° C or more and less than 230 ° C to produce a lower condensation product; A step of discharging and cooling the lower condensate at an atmospheric pressure or lower in an inert gas atmosphere; And subjecting the lowered condensate discharged and cooled to solid-state polymerization. In the above production method, polyamide excellent in mechanical strength, heat resistance and color tone can be obtained without problems such as gelation. |
