ABSTRACT:
A novel aromatic polyamide crystalline complex capable of being molded at low temperatures is produced by contacting an aromatic polyamide in which at least 75 mol % of repeating unit comprises m-phenyleneisophthalamide with at least one member selected from the group consisting of hexamethylphosphoric amide, N-methyl-2-pyrrolidone, .epsilon.-caprolactam and 2-pyrrolidone to form a crystalline complex and then removing the hexamethylphosphoric amide, N-methyl-2-pyrrolidone, .epsilon.-caprolactam and 2-pyrrolidone which are not contained in the crystal.
