| titleOfInvention | The manufacture method of polyamide |
| abstract | The present invention provides a kind of manufacture method of polyamide, this method manufacture tone is improved and favourable polyamide in quality, it is characterized in that, in the method for the polyamide that fusing point is more than 255 DEG C is manufactured using the progress polycondensation of intermittent reaction device using the mixing benzene dimethylamine comprising p dimethylamine as diamine component and dicarboxylic acid component, more than 0.1MPaG the following maintenance reaction mixture of pressurization molten condition side to the temperature for being heated to more than fusing point and maintain diamine component is added dropwise in the dicarboxylic acid component of molten condition when, the temperature of reactant mixture is maintained untill less than the 255 DEG C mol ratios (diamine component/dicarboxylic acid component) until reactant mixture reach 0.8, the temperature for making reactant mixture during completion of dropwise addition is more than the fusing point of foregoing polyamides. |
