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.

A resin composition for primer use is described, which contains a copolymer of (I) a radical-polymerizable olefin resin and (c) a monomer copolymerizable with said olefin resin (I) and containing an alkyl (meth)acrylate and/or a fluorine-containing unsaturated monomer as essential ingredients, said radical-polymerizable olefin resin (I) being a product of the reaction of (a) an olefin resin having at least one functional group per molecule with (b) a radical-polymerizable monomer having a functional group reactive to the functional group contained in said olefin resin (a). A primer composition is also described.
