ABSTRACT:
N-(Substituted phosphinyl) polyamides and a method for their production are disclosed. The N-(substituted phosphinyl) polyamides are characterized by the recurring unit structure represented by the formula ##STR1## wherein A is in part hydrogen and in part a substituted phosphinyl radical. One method of producing the N-(substituted phosphinyl) polyamides is treating N-chlorinated polyamide with substituted phosphinyl compounds. The disclosed N-(substituted phosphinyl) polyamides exhibit excellent thermal stability fire resistance, good processability, high water absorption and permeability. The N-(substituted phosphinyl) polyamides are useful for making flame resistant textile materials.
