Abstract
Controlled geometry particles of thermoplastic polymers are prepared from compositions containing the thermoplastic polymer and two additives, in the molten state, by cooling the molten composition and disintegrating the resulting dispersion of thermoplastic polymer; powders obtained therefrom advantageously have mean particle diameters ranging from 0.1 to 800 μm and are useful additives in, e.g., paints and coatings.
