ABSTRACT:
A new benzidine monomer composition containing an asymmetrically situated benzamide (iminobenzoyl) group: ##STR1## was prepared from the benzolyation reaction of 4,4'-dinitro-2-biphenylamine and benzoyl chloride, followed by catalytic hydrogenation. The compound can be used as a comonomer in the preparation of soluble thermoplastic polyamides, polyimides and other high performance polymers whose preparations require a diamine monomer.
