Flammability and weight loss reduced. Fire-resistant polymers obtained from 1-{(dialkoxyphosphonyl) methyl}-2, 4- and -2, 6-diaminobenzenes by reaction with acyl or diacyl halides of higher functionality. Incorporation of compounds containing phosphorus into certain polymers shown previously to increase fire retardance. Discovery adds new class of polyamides to group of such polymers.
