摘要： The invention discloses a process for the production of a particulate polymer which contains few fine particles and has a narrow particle size distribution and a controlled bulk specific gravity. Characteristic features of the process of this invention reside in that a polymer latex obtained by emulsion polymerization is successively processed through the following steps (I) and (II):Step (I) The polymer latex is coagulated into a slurry in which particles thus coagulated are dispersed in water.Step (II) The slurry obtained in Step (I), an organic liquid almost insoluble in water and incapable of dissolving the polymer and water are mixed for granulation under the conditions that(a) The proportion of water in the whole mixture is 50-85 wt. %,(b) The amount of the organic liquid is 15-150 parts by weight per 100 parts by weight of the polymer in the polymer latex, and(c) The temperature T (.degree.C.) of the whole mixture is maintained for 0.5 minute to 1 hour on average within the range of the following equation:A-40.ltoreq.T.ltoreq.A wherein A means the azeotropic temperature (.degree.C.) of the mixture.In the above process, control of the interfacial tension between the organic liquid and the dispersion medium of the slurry within a specific range has made it possible to control the particle size of the resulting particulate polymer to a desired level.

摘要： Disclosed herein is a particulate polymer prepared by the agglomeration of polymer particles contained in a polymer latex. The particulate polymer is composed of primary particles having particle sizes of at least 20 .mu.m and/or secondary particles formed by the agglomeration of at least some of the primary particles and is in the form of a compact mass substantially free of voids. The particulate polymer is prepared by coagulating the polymer latex in the presence of a coagulant and an organic liquid having low solubility in water. The particulate polymer has a high bulk specific gravity and contains few fine particles. It is thus easy to handle and allows the consumption of energy to be reduced in the drying step.
