| titleOfInvention | Process for producing polyamide |
| abstract | A process for producing a batch-wise polyamide by which a diamine component containing p-xylylenediamine and a dicarboxylic acid component are melt-polymerized directly in the absence of a substantial solvent, characterized in that a massive adherence to a stirring device is suppressed The present invention also provides a batch-wise production method of polyamide, which improves the efficiency and which minimizes incorporation of unmelted material resulting from the adherend among the obtained products.n n n Production of a polyamide which directly melts and polymerizes a diamine component and a dicarboxylic acid component containing 70 mol% or more of xylylenediamine containing 20 mol% or more of p-xylylenediamine in a batch reactor in the absence of a substantial solvent (1) a rotating shaft connected to a stirring driving unit, (2) a columnar body or a plate-like body moving on a circumference about the rotation axis, and a stirring device for stirring the molten polymer in the apparatus, And (3) a connecting member connecting the rotating shaft and the stirrer, wherein the distance between the center line of the rotating shaft and the center line of each of the two or more stirring rods is 15% or more of the inner diameter of the reaction apparatus, , And the stirring is performed so that the connecting member and the rotating shaft are disposed above the molten polymer liquid surface (liquid surface) and the peripheral speed of the stirring rod is 30 m / min or more ≪ / RTI > |
