Treatment of hazardous material with vapor suppressing, persistent, water- containing, polymeric air foam

Air is mechanically entrained in an aqueous solution of surfactant and poly(oxyalkylene) polyisocyanate polymer, the poly(oxyalkylene) portion of which contains sufficient oxyethylene units to render the polymer water-soluble and hydroph...
