摘要：A process is described for producing a dispersion of a condensation polymer ina hydrocarbon or chlorinated hydrocarbon liquid in which the polymer is insoluble, thedisperse particles of polymer incorporating a pigment, filler or like modifying agent. Atleast one of the reactants from which the polymer is to be derived is heated in the liquidin the form of the liquid disperse phase of an emulsion in that liquid, made with the aid ofa specified emulsifying agent, and the modifying agent is dispersed in that liquid dispersephase prior to completion of the polymer-forming reaction.
