Abstract
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.
