Abstract

PURPOSE: To readily and simply obtain pulp of an aromatic polyamide, having good shape, by respectively specifying a raw material, solvent therefor and composition and temperature of a coagulating solution.
CONSTITUTION: An aromatic polyamide synthesized from an aromatic polyfunctional isocyanate and aromatic polyfunctional carboxylic acid is dissolved in N,N'-dimethylethyleneurea to gove a dope, which is then introduced into a coagulating solution in a vigorously stirred state. The coagulating solution is constituted of N,N'-dimethylethyleneurea and a nonsolvent for the aromatic polyamide, e.g. water or methanol. The content of the N,N'-dimethylethyleneurea is 3W14wt% and the temperature is ≤35°C. Paper produced by using the resultant pulp has good dielectric breakdown voltage and hue.
