Abstract
A process for producing an acrylic and/or methacrylic polymer based preparation for the surface treatment of zinc consists in polymerizing at least one (meth)acrylic acid and at least one (meth)acrylate in a mixture of organic cosolvents. The preparation is then formed from the resultant copolymer in the cosolvents by dilution in a quantity of water and preferably an excess of water with respect to the cosolvents in the polymerization stage.
