Abstract

PURPOSE:To continuously polymerize monomers into a wholly arom. polyamide stably for a long period of time with an economically advantageous high monomer concn. on an industrial scale, by using a specified feeding temp. of a soln. of an arom. diamine at the inlet of a polymn. apparatus. CONSTITUTION:A molten liquid of an arom. dicarboxylic acid chloride, and a soln. of an arom. diamine substantially perfectly dissolved in an N-substd. amide solvent are respectively, and continuously fed into a polymn. apparatus at a substantially equimolar ratio of the chloride groups of the arom. dicarboxylic acid chloride to the amino groups of the arom. diamine to effect a reaction therein. The feeding temp. of the soln. of the arom. diamine is set to be higher than the m.p. of the arom. dicarboxylic acid chloride. As the N- substd. amide solvent, use is pref. made of a system of N-methyl-2-pyrrolidone, N,N-dimethylacetamide or N-acetylpyrrolidine admixed with calcium chloride or lithium chloride.
