ABSTRACT:
Flame-retardant polyols are produced by chemically reacting an epoxy compound, a phosphorus-containing compound and a compound containing 1 or more active hydrogens to produce a phosphorus-containing polyol with acid radicals which are reacted with an alkali compound. The flame-retardant polyol will react with polyisocyanates to produce solid or foamed products which may be used as coating agents, adhesive or for insulation.
