[0042] Embodiment A1~A4: Preparation of PA10T Polyamide Resin A
[0043] In the pressure kettle equipped with magnetic coupling stirring, condenser tube, gas phase port, feeding port and pressure explosion-proof port, add the reaction raw materials according to the ratio in Table 1, and then add benzoic acid, sodium hypophosphite and deionized water; weight of sodium hypophosphite In order to remove 0.1% of the weight of other materials except the ionized water, the weight of deionized water is 30% of the total weight of the materials; vacuum is filled with high-purity nitrogen as protective gas, and the temperature is raised to 220 in 2 hours under stirring. o C, put the reaction mixture at 220 oC stirred for 1 hour, then the temperature of the reaction was raised to 230 with stirring o C; reaction at 230 o The constant temperature of C and the constant pressure of 2.2Mpa were continued for 2 hours, and the pressure was kept constant by removing the water formed. After the...
