Abstract
A first stable suspension of at least one solid monomer, capable of being polymerized to a condensation polymer when heated, is formed in a first organic liquid inert during polymerization and containing a minor amount of a dispersing agent stable during said polymerization. A second stable suspension of finely divided inorganic particles in a second organic liquid inert during said polymerization and miscible with said first organic liquid, is formed and contains a minor amount of a dispersing agent. The first suspension is then added to the second suspension while stirring and heating the second suspension to the polymerization temperature of the monomer.
