ABSTRACT:
A method for preparing granular calcium hypochlorite treated with polyfluorinated polymer is disclosed. The treated product may be compressed and formed into shaped articles. A method described comprises spraying a suspension of polyfluorinated polymer, e.g., polytetrafluoroethylene, onto granular calcium hypochlorite in a continuous or batch blender. Tablets prepared from the granular hypochlorite so surface treated with polyfluorinated polymer dissolve in water at a rate slower than tablets prepared from granular calcium hypochlorite having polyfluorinated polymer dispersed throughout the granules. Granular calcium hypochlorite having a particle size range of -6, +100 U.S. Sieve Series having from about 0.005 to 0.5 weight percent polyfluorinated polymer on its surface are described.
