Abstract

Procedure for manufacturing dispersions of thermoplastic or thermoelastic synthetic materials to form powders with a low content of water precipitation agent and a unit grain size, characterized in that the polymer dispersions and precipitating agent are mixed intimately under high turbulence; precipitating and maintaining high turbulence is carried out at a temperature below the polymer sintering temperature; the polymer particles agglomerate in a precipitating fleet on one or more steps with less and less turbulence and harden; The precipitation fleet and the agglomerated polymer particles are separated.
