Abstract
In a particulate additive for water for fire fighting containing a strongly swelling water-insoluble high molecular weight polymer as gelatinizing agent, the improvement which comprises a water-soluble release agent which does not cause the particles of said gelatinizing agent to swell, the particles of the gelatinizing agent being encased or dispersed in the release agent. Suitable release agents include polyethylene glycol, diammonium biphosphate, sugars, mannitol, etc. The gelatinizing agent may be a moderately cross-linked water-insoluble acrylic or methacrylic acid copolymer.
