Abstract
(Co)polymer particulates soluble in their corresponding (co)monomer composition, e.g., particulates of acrylic, methacrylic or styrene polymers, are produced by finely dispersing an aqueous phase including at least one polymerization initiator in an organic phase which comprises such (co)monomer composition and at least one nonsolvent for such (co)polymer which is miscible with such (co)monomer composition, and suspended emulsion polymerizing such mixed-phase polymerization recipe.
