Abstract
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.
