  • Process for the production of a dispersion of condensation polymer particles containing a modifying agent
    Patent number: 3985700
    Abstract: A process is described for producing a dispersion of a condensation polymer in a hydrocarbon or chlorinated hydrocarbon liquid in which the polymer is insoluble, the disperse particles of polymer incorporating a pigment, filler or like modifying agent. At least one of the reactants from which the polymer is to be derived is heated in the liquid in the form of the liquid disperse phase of an emulsion in that liquid, made with the aid of a specified emulsifying agent, and the modifying agent is dispersed in that liquid disperse phase prior to completion of the polymer-forming reaction.
