Abstract: A process for the neutralisation or slight basification of aqueous dispersions of film forming copolymers containing carboxylic groups with an alkali metal hydroxide is claimed. The aqueous copolymer dispersion is strongly mixed with a dilute, aqueous alkali metal hydroxide solution under static pH control such that during the addition the pH does not exceed 7.9 and the final pH is 7.0-7.9. An Independent claim is included for a coating composition for mineral based molded articles prepared using the neutralized polymer dispersion.

Abstract: The invention relates to an aqueous polymer dispersion which may optionally contain mineral additives and/or pigments and which essentially consists of a mixture of A) a 20% to 65% w/w aqueous dispersion of a copolymer of (a) an olefinically unsaturated compound containing one or more carboxyl groups and/or amide groups, and (b) at least two monomers selected from the group consisting of acrylates and methacrylates and vinylaromatic compounds, and B) from 0.1 to 5% w/w, based on the weight of the copolymer contained in component (A), of at least one aromatic ketone of the general formula (I) aryl radical and R1 stands for an aryl radical containing from 1 to 3 radicals of the formula -O-C(O)-O- attached to one or more oxaalkylene groups. Such polymer dispersions are suitable for the manufacture of paints and coating systems.
