    摘要: The invention relates to a superabsorbent polymer wherein an increased rate of water absorption is obtained by the addition of an encapsulated blowing agent. The invention relates to a superabsorbent polymer including an encapsulating blowing agent and having a vortex time of 40 seconds or less. In particular, the superabsorbent polymer includes 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; wherein the wherein the composition has a degree of neutralization of more than about 20%; and from about 0.05 to about 10.0 wt. % of an encapsulated blowing agent.

    摘要: 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.
