Abstract
Abstract Aqueous cross-linking co-polymer dispersions are prepared using emulsion polymerization techniques with an anionic emulsifier from a monomer blend as follows: 25 - 35 % BY WEIGHT OF BUTYLMETHACRYLATE 10 - 25 % BY WEIGHT OF ETHYLHEXYLACRYLATE AND/OR N-BUTYLACRYLATE 10 - 20 % BY WEIGHT METHYLMETHACRYLATE 10 - 20 % BY WEIGHT STYROL 1 - 3 % BY WEIGHT METHYACRYLIC ACID AND/OR ACRYLIC ACID 10 - 25 % BY WEIGHT POLYPROPYLENE GLYCOL MONOMETHACRYLATE AND/OR POLYETHYLENE GLYCOL MONOMETHACRYLATE Paint compositions comprising the above dispersions and amineformaldehyde resins have excellent weather resistance, flexibility, scratch resistance, adhesion, and freeness from craters.
