ABSTRACT OF THE DISCLOSURE A flexible polyacid containing at least one phosphorus and/or halogen-containing component may be pre- pared readily by (1) mixing together in bulk, solution or dispersion a polyacid and at least one of six hereinafter- named components and (2) drying or conditioning the mixture. The component may be selected from the group consisting of (A) at least one di(polyoxyethylene)hydroxymethyl phosphonate having the formula HOCH2P(O)[O(C2H4O)kH]2 wherein k is from 1 to 5, (B) at least one compound having the formula Image wherein the sum of m and n is from 1 to 35 (C) tetrakis (hydroxymethyl)phosphonium chloride [(HOCH2)4PCl], (D) a mixture of from about 75% to about 100% by weight 2,2-bis- (bromomsthyl)-1,3-propanediol, from about 0% to about 10 by weight monobromoneopentyl triol, and from about 0% to about 20% by weight tribromoneopentyl alcohol (E) diethyl ethyl phosphonate [C2H5P(O)(OC2H5)2], and (F) a compound having the formula (RO)qP(O)[O(C2H4O)rH]3-q wherein R is an alkyl group containing from 1 to 5 carbon atoms, q is 1 or 2, and r is from 1 to 4.
