PROCESS FOR PREPARING A STABLE DISPERSION IN AN INERT ORGANIC LIQUID OF PARTICLES COMPOSING OF A POLYMER FROM ONE OR MORE MONOMERS, OF WHICH AT LEAST ONE MELTING POINT ABOVE THE POLYMERIZATION TEMPERATURE AND INSOLUBLICALLY INSOLUBLY A MODIFYING PRODUCT, AND PRODUCED SHAPES THEREOF.

A process for manufacturing a stable dispersion in an organic liquid of particles consisting of (a) a polymer insoluble in the liquid and formed by polymerization of monomer(s) at least one of which is solid at the polymerization temperature and (b) sub-particles of a solid modifying agent for the polymer, the process comprising dispersing the solid monomer and the modifying agent together in the liquid in the presence of a specified dispersing agent so as to form a stable dispersion of solid particles not larger than 50 mu , and heating the dispersion together with any other monomers required, so as to bring about polymerization, in the presence of a specified stabilizing agent for the polymer formed. The functions of dispersing agent and stabilizing agent may be combined in a single substance.
