ABSTRACT:
A method is provided for the production and processing of mixtures of pluralities of components based upon reactant synthetic resins, wherein the mixture or at least a part of the components thereof is cooled by addition, and mixing in, of cryogenic liquid gas before or during the subsequent treatment of the mixture until a temperature is reached which allows an essentially dry treatment subsequently. The reactant plastic mixture can be cooled in the liquid state by cryogenic liquid gas to provide granulation or pulverization by cold shock. The mixture can also be cooled by the introduction thereof into a bath of cryogenic liquid gas. The mixture can also be sprayed under pressure, with the sprayed particles then being cooled directly, or indirectly, by cryogenic liquid gas.
