摘要： In the production method of polyamide of the present invention, the mole balance at a set point during melt polymerization is estimated from a pre-established equation for calculating the mole balance during melt polymerization from a melt viscosity. On the basis of the estimated mole balance, the subsequent conditions of melt polymerization of a batch and the polymerization conditions of the next and subsequent batches are determined. In addition, the mole balance, molecular weight and relative viscosity of melt-polymerized polyamide are estimated from pre-established equations each for respectively calculating the mole balance, molecular weight and relative viscosity at the end point of melt polymerization from the melt viscosity. The conditions for solid phase-polymerizing the melt-polymerized polyamide are determined on the basis of estimated values.

摘要： In the process for producing polyamide of the present invention, a diamine and a dicarboxylic acid are melt-polycondensed in a batch-wise fist polymerizer in the absence of a solvent to produce a middle-stage polyamide. The diamine has a boiling point higher than a melting point of the middle-stage polyamide being produced under inner pressures of the first polymerizer. The middle-stage polyamide is fed into a continuous second polymerizer while controlling the change of relative viscosity within ±0.2, and further polycondensed there to produce the objective polyamide. With such a process, the change of polymerization degree of the middle-stage polyamide during the switching of the polymerization step from a batch-wise manner to a continuous manner is avoided, thereby preventing the variation in quality of the final product.

摘要： In a repeated batch production of polyamide, a dicarboxylic acid component and a diamine component fed to a batch reactor are melt-polymerized in the absence of solvent. After adding the diamine component to the molten dicarboxylic acid component, the melt polymerization is further continued at a temperature equal to or higher than the melting point of polyamide being produced for at least 10 min while maintaining the pressure of the vapor phase in the batch reactor at higher than 0.1 MPaG by introducing water vapor. The polyamide thus produced is hardly affected by gels even when the melt polymerization is conducted in the presence of polyamide remaining after the previous batch production. Molded articles thereof contain little fisheyes.
