    • A process for producing a thermoplastic polymer powder which comprises adding a polymer (B) and/or an inorganic compound (C) to a coagulation slurry or a powder of a thermoplastic polymer (A) obtained from emulsion polymerization and having a glass transition temperature Tg defined by the following equation (1), in an amount of 0.1-10 parts by weight to 100 parts by weight of the thermoplastic polymer (A), compacting the thermoplastic polymer (A) at a temperature in a range of (Tg-30) to (Tg+50).degree. C., and comminuting it:Tg=W.sub.1 .times.Tg.sub.1 +W.sub.2 .times.Tg.sub.2 + . . . +W.sub.n .times.Tg.sub.n ( 1)wherein n is the number of the monomers forming the thermoplastic polymer (A); W.sub.1, W.sub.2, . . . W.sub.n each represents weight fraction of each monomer i (i=1, 2, . . . n) in the polymer (A); and Tg.sub.1, Tg.sub.2, . . . Tg.sub.n each represents the glass transition temperature of the polymer composed of each monomer i. According to the present invention, it is possible to remarkably enhance bulk specific gravity of thermoplastic polymers as compared with the case using the methods known in the art.
