    摘要: A process for producing a powdered carboxyl-containing polymer comprising mixing a solution of a water-insoluble polymer containing a carboxyl group per molecule in a hydrophilic organic solvent (e.g., ethanol) and an aqueous solution of a dispersant comprising a neutralized copolymer of a carboxyl-containing unsaturated monomer and a (meth)acrylic ester to precipitate the water-insoluble polymer. Fine polymer particles free from adhesion or agglomeration are obtained efficiently. Since any residual unreacted carboxyl-containing monomers are dissolved out in water as a precipitating solvent, the resulting powdered polymer has a reduced residual content of the unreacted monomers which may be poisonous and is therefore useful as a base resin of cosmetics or a coating resin for applications involving contact with the skin.
