FIELD: process engineering.SUBSTANCE: disperse powders are produced by spray drying of aqueous polymer dispersions and adding of anti-caking means. Claimed process differs from know methods in that sintered anti-caking means with particle size of 10-250 mcm or 5 mm to 5 cm in the case of extruded mixes are forced, completely or partially, into spray drying process. Then, said means are ground to particle size of 0.01-5 mcm, or in the case of extruded articles, to 2-60 mcm.EFFECT: perfected method.15 cl, 2 dwg |
