description The invention discloses a reaction and separation coupled polyamide continuous polycondensation method, and belongs to the technical field of chemical production. The polycondensation method comprises the following steps: S1, introducing a polyamide salt solution and polycondensation water into the rectifying tower in a liquid phase form; s2, all the components introduced into the rectifying tower are separated according to different relative volatility degrees, diamine and a polyamide salt solution enter a coupling reactor, and a liquid phase existing in the coupling reactor comprises polyamide salt, water and polycondensate. According to the invention, diamine and water are introduced into the rectifying tower part by the coupling reactor, recycling and reusing of diamine and removal of water are realized, and due to the fact that polycondensation reaction is a balanced reaction, the removal of water and recycling and reusing of diamine can enable the polycondensation reaction to be carried out towards the
