Abstract
Aqueous dispersion of a polymer, which polymer has been obtained by subjecting a starting polymer which contains maleic anhydride monomer units and vinyl aromatic monomer units to an imidization reaction, the starting polymer containing 7-50 mole % maleic anhydride monomer units and the imidization reaction having been carried out in such a way that at most 75% of the maleic anhydride monomer units has been imidized.
