Abstract: Fire protection and/or fire fighting additives including a water-swellable polymer, a water immiscible phase, an emulsifier, an inverter, and a remainder water are disclosed. The water-swellable polymer is acrylamide-free and crosslinked and may be prepared by inverse phase polymerization. Such fire protection and/or fire fighting additives and fire protection and/or fire fighting compositions made using the additives exhibit exceptionally low corrosion properties. For example, when contacted with any one of a 2024-T3 aluminum alloy, 4130 steel, yellow brass, or AZ31B magnesium alloy, the corrosion rate is less than about 5 mils/yr for the fire protection and/or fire fighting additives.

Abstract: The invention relates to a superabsorbent polymer comprising a composition comprising a polymeric resin composition comprising from about 55 to about 99.9 wt. % of polymerizable unsaturated acid group containing monomers, from about 0.001 to about 5.0 wt. % of internal crosslinking agent and from 0 to 25 wt % of a preneutralizing agent; wherein the polymeric resin composition is preneutralized from 0 to about 50 mole %; and a water swellable, water-insoluble aminopolysaccaride polymer wherein when the superabsorbent polymer is contacted with an aqueous solution, the polymeric resin composition is neutralized by the aminopolysaccaride polymer so that the superabsorbent polymer has a degree of neutralization of about 20 mole % or more than the preneutralization degree of the polymeric resin composition.

Abstract: A polyamphoteric superabsorbent copolymer made up of polymerizerable acid monomer and of polymerizable base monomer and optionally a supplemental monomer. In particular, the invention includes a radiation curable coating composition that comprises from about 20 weight % to about 80 weight % of polymerizerable acid monomer and from about 20 weight % to about 80 weight of polymerizable base monomer; and from 0 weight % to about 50 weight % of supplemental monomer. On exposure to radiation the coating composition forms a polyamphoteric superabsorbent copolymer. The radiation curable coating composition may be used with suitable substrates.
