ABSTRACT:
Aromatic-aliphatic diamines of the formula ##STR1## in which Ar is an arylene or substituted arylene are useful in preparing thermally stable, rigid, polyamides, polyureas and polyurethanes having a repeating unit of the formula ##STR2## in which Ar is arylene or substituted arylene, X is --NH-- or --O--, n is 0 or 1, and R is a divalent organic radical. Polymers of this invention can be melt-spun into thermally stable fibers.
