Abstract:
1. An aqueous polymer dispersion obtained by free-radically initiated emulsion polymerization of (a) from 19.9 to 80 parts by weight of at least one vinylaromatic compound, (b) from 19.9 to 80 parts by weight of at least one acrylate monomer selected from the group consisting of a C1-C10 alkyl acrylate and a C1-C10 alkyl methacrylate, (c) from 0.1 to 10 parts by weight of at least one ethylenically unsaturated acid, and (d) from 0 to 20 parts by weight of at least one additional ethylenically unsaturated monomer, wherein a sum total of monomers (a), (b), (c), and (d) is 100, and the free-radically initiated emulsion polymerization is effected in an aqueous medium in a presence of a free-radical initiator, seed latex, and at least one carbohydrate compound in a form of a degraded starch.
