  • Patent number: 7888439
    Abstract: A process for the production of aqueous binder latices by multistage emulsion polymerization in the aqueous phase, comprising the successive steps: 1) free-radical polymerization of a monomer mixture A comprising acidic monomers in a proportion corresponding to an acid value of 10 to 100 mg of KOH/g and olefinically polyunsaturated monomers in a proportion of 0.5 to 5 wt %, 2) neutralization of acid groups of the polymer formed in process step 1) and 3) free-radical polymerization of at least one monomer mixture B comprising acidic monomers in a proportion corresponding to an acid value of mixture(s) B of 0 to below 5 mg of KOH/g, hydroxyl-functional monomers in a proportion corresponding to a hydroxyl value of mixture(s) B of 0 to below 5 mg of KOH/g and olefinically polyunsaturated monomers in a proportion of 0.
