Abstract

Described herein is a process for preparing a pulverulent composition which has inhibitory properties on monomer polymerization and which has a melting temperature Mp, said process comprising: i) the introduction into a mixer, the chamber of which has been preheated to a temperature T below Mp, of at least two polymerization-inhibiting elementary solids, said solids being introduced separately into said mixer in pulverulent form, ii) the mixing in said mixer, in the absence of any external liquid phase, of said solids at a temperature T below the temperature Mp, at least one of said polymerization-inhibiting elementary solids being introduced into said mixer at a temperature Ti such that the mixing is carried out under isothermal conditions at a temperature fixed at said temperature T, and iii) the recovery of said pulverulent composition.
