[0042] The embodiment of the present invention also provides the preparation method of described dipolyamine modified copolyamide, comprising the following steps:
[0043] (1) Turn on the reactor to stir, and add the organic amine to the reactor;
[0044] (2) Add the organic acid to the completed system of step (1), and wait for the self-reaction heating temperature of the system to no longer rise;
[0045] (3) Turn on the reaction kettle to heat up, so that the system can complete the reaction at 140-260°C;
[0046] (4) When the reaction temperature is >180°C, control the pressure of the reactor at 1×10 2 ~1.013×10 5 Pa, after polycondensation until the required viscosity is reached, the material is discharged to obtain the copolyamide modified by dipolyamine.
