Abstract
A phosphorus-containing flame retardant for synthetic resins is produced when suitable amounts of a phosphorus oxide compound of the formula (P.sub.2 O.sub.5).sub.0.5.sub.-1.0 (H.sub.2 O).sub.0.0.sub.-1.5, melamine, and at least one saturated open-chain polyol containing from 5 to 15 carbon atoms and from 4 to 8 hydroxyl groups are combined and heated under such conditions that the resulting product when incorporated into a synthetic resin will not cause significant foaming of the synthetic resin composition when it is subjected to molding conditions but will still impart flame resistance to said synthetic resin.
