A process is described for the production of a stable dispersion of a copolymer, in particular of a copolyester, copolyamide or copolyesteramide, in a non-solvent organic liquid. The process involves the steps of (1) dispersing two or more comonomers, each of which is capable of undergoing homopolymerization and is solid at the copolymerization temperature, in the liquid with the aid of a defined monomer-stabilizing agent and so as to produce monomer particles no larger than 50 mu , and (2) heating the dispersion so obtained so as to bring about copolymerization, in the presence of a defined polymer-stabilizing agent. The copolymers so produced are believed to be different in structure from those obtained from the same comonomers by melt or solution copolymerization. |
