Particulate nonrubber materials derived from serums byproduced during coagulation of nayrual rubber latexes consist essentially of nonrubber components present in those serums and have an average particle size of 10 to 100 microns. The materials are suitable for instance for rubber products and pharmaceuticals manufacture, and may be produced by spray-drying the serums at 150 DEG to 250 DEG C. |
