Abstract

PURPOSE: A solution of specific aromatic polyamide polymer and a precipitant are mixed under high shear force conditions to produce the titled substance with good water filtration, paper-making properties, less fluctuation in paper thickness and showing high physical properties such as electric insulation after processed.
CONSTITUTION: The reaction between an aromatic polycarboxylic acid such as isophthalic acid and an aromatic polyisocyanate such as tolylene-2,6-diisocyanate is conducted in an anhydrous organic polar solvent such as N,N-dimethylacetamide in an inert gas atmosphere or under reduced pressure in the presence of a catalyst of a monoalkali salt of organic polycarboxylic acid at 20W250°C under heating to prepare a 2W40wt% solution of an aromatic polyamide of more than 0.5 inherent viscosity. The resultant polymer solution is mixed with a precipitant, preferably a mixture of water (5W90wt%) with an inorganic compound such as calcium chloride under a shear force of higher than 3,000 Leynold's number at 35W95°C.
