| titleOfInvention | High-washability aqueous polymer dispersion, preparation and use thereof as binder in coating compositions |
| abstract | Aqueous polymer dispersion prepared from a monomer mixture comprising an alkyl (meth)acrylate, a vinylaromatic monomer, a short-chain alpha , beta -unsaturated mono- or dicarboxylic acid and an ethylenically unsaturated carbonyl compound with at least one alpha hydrogen atom is produced by adding the monomer mixture to a reaction medium comprising the monomer mixture in prepolymerized form. Aqueous polymer dispersion prepared from a monomer mixture comprising 50-99.99 wt.% of a 1-12C alkyl (meth)acrylate, 0-40 wt.% of a vinylaromatic monomer, 0-5 wt.% of a short-chain alpha , beta -unsaturated mono- or dicarboxylic acid and 0.01-5 wt.% of an ethylenically unsaturated carbonyl compound with at least one alpha hydrogen atom is produced by adding 80-98% of the monomer mixture to a reaction medium comprising 2-20 of the monomer mixture in prepolymerized form. Independent claims are also included for: (1) A process for producing the polymer dispersion, comprising: (a) prepolymerizing an emulsion comprising 2-20% of the monomer mixture so that the overall monomer conversion is 50-100%; (b) adding an emulsion comprising 40-49% of the monomer mixture over 45-180 minutes and continuing polymerization for 0-60 minutes; and (c) adding an emulsion comprising 40-49% of the monomer mixture over 45-180 minutes and continuing polymerization for 0-60 minutes; (2) A paint composition comprising the polymer dispersion as a binder |
