Abstract:
The invention relates to a process for the preparation of particles based on a thermoplastic polymer with a mean diameter of less than 1 mm. The process of the invention comprises more particularly a stage of preparation of a composition comprising the thermoplastic polymer and an additive, in the molten state, of cooling the composition and of disintegration of the thermoplastic polymer dispersion.
