Description

Abstract of the Invention 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 polymerisation of monomer(s) at least one of which is solid at the polymer- isation 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 50µ, and heating the dispersion together with any other monomers required, so as to bring about polymerisation, in the presence of a specified stabilising agent for the polymer formed. The functions of dispersing agent and stabilising agent may be combined in a single substance.
