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.
