ABSTRACT:
An aromatic polyamide comprising (1) a unit of the formula: ##STR1## and (2) a unit of the formula: ##STR2## and being excellent in strength, rigidity and heat resistance and improved in light resistance, flexibility and wear resistance, which can be produced by polycondensation of a diamine component comprising N,N'-bis(p-aminobenzoyl)-ethylenediamine and p-phenylenediamine, the content of the N,N'-bis (p-aminobenzoyl)ethylenediamine being from about 0.6 to 50 mol %, with a dicarboxylic acid component comprising terephthalic acid or its reactive derivative in a substantially equimolar amount to the diamine component in an amide polar solvent.
