Abstract : The present invention relates to the synthesis of fluoroaliphatic polyamides and monomers thereof. Novel fluorodiamines having the following structure: NH2(CH2)(x)OCNH(CH2)(y)(CF2)(n)(CH2)(z)NHCO(CH2)(x)NH2 and acid salts thereof, wherein n, x, y, and z are integers equal to or greater than 1, methods of making these fluorodiamines, fluorinated polyamides produced from these fluorodiamines, and methods of making these polymers, are disclosed. In one example, an alkyl fluorodiamine is reacted with an active ester of an omega amino acid blocked with by a carbobenzoxy group at one end and esterified to a p-nitrophenol group at the other. The reaction product is acidified to produce the fluorodiamine acid salt. This fluorodiamine acid salt is condensed with an acid chloride to produce a novel fluorinated polyamide. The novel fluorinated polyamides may be used, for example, in ropes for anchoring ships. Keywords: Nylon, Acid halides, Patent applications. (aw)
