Abstract
The present invention relates to a process for preparing polymer latex resin powder, and particularly to a process for preparing polymer latex resin powder including coagulating polymer latex and aging the polymer latex. The process further includes introducing an emulsifier into polymer latex emulsion before coagulation. The polymer latex resin powder prepared by the present invention has 85 wt % or more of particles with diameter of 70 to 400 μm, each 10 wt % or less of fine powder with less than 70 μm and those with 400 μm or more, and it has superior bulk density and caking property.
