In the prevention of the spread of fires and for directly fighting fires, a cross-linked, water-swellable additive polymer in water/oil emulsion produced by an inverse phase polymerization reaction to be added to the firefighting water is disclosed. The additive has the properties of absorbing large quantities of water, high viscosity for adherence to vertical and horizontal surfaces, and retention of sufficient fluidity to be educted in standard firefighting equipment. The method of adding this additive to the firefighting water by eduction or by a batch addition to the water source is also disclosed.

[ We claim:] [1.]1. A method for applying polymer particles to a surface to combat fires, said method comprising:(a) providing cross-linked polymer particles made by an inverse phase polymerization reaction and having a water-in-oil emulsion form;(b) adding said water-in-oil emulsion as a water-absorbent additive to water in an amount sufficient to increase the viscosity of the resulting water-additive mixture to above 100 mPa.multidot.s, and wherein said water-absorbent additive is present in sufficient quantity such that after absorption of water said water-absorbent additive holds more than about 50% by weight of the total water; and(c) directing said water-additive mixture onto said surface.
