摘要：Disclosed herein is a particulate polymer prepared by the agglomeration ofpolymer particles contained in a polymer latex. The particulate polymer is composed ofprimary particles having particle sizes of at least 20 &mgr;m and/or secondary particlesformed by the agglomeration of at least some of the primary particles and is in the formof a compact mass substantially free of voids. The particulate polymer is prepared bycoagulating the polymer latex in the presence of a coagulant and an organic liquid havinglow solubility in water. The particulate polymer has a high bulk specific gravity andcontains few fine particles. It is thus easy to handle and allows the consumption of energyto be reduced in the drying step.
