A process for the preparation of a linear polyamide by reacting the appropriate dicarboxylic acid and diamine in a liquid reaction medium with the addition of a catalytically effective phosphorus compound, removing the reaction medium to give a solid salt, precondensing the latter in the solid phase at a temperature of from 140.degree. C. to 5.degree. C. below the melting point of the salt and continuing condensation at a temperature above that used for the precondensation until the desired degree of condensation is reached.
