The present invention relates to a polymer dispersion comprising A) at least one first phase comprising a) at least one chain growth addition polymer P constructed from 1 to 99.9 wt % of at least one ester from ethylenically unsaturated monomers, as monomer A, 0 to 20 wt % of at least one ethylenically unsaturated carbonitrile, as monomer B, 0.1 to 5 wt % of at least one acid-functional ethylenically unsaturated monomer, as monomer C, 0 to 5 wt % of at least one monomer which, alone or with a crosslinking agent, has crosslinking effect and which is different from the monomers A to C, as monomer D, 0 to 20 wt % of at least one ethylenically unsaturated monomer which forms a chain growth addition homopolymer having a glass transition temperature &#x2265;50&#xb0; C. and which is different from the monomers A to D, as monomer E, the sum of the total amount of the monomers A to E making 100 wt %, a1) optionally at least one polymer seed, b) 10 to 60 parts by weight, based on 100 parts by weight of polymer P, of at least one saccharide compound S, and B) a second phase comprising c) at least one solvent. The present invention also relates to a method for producing the polymer dispersion of the invention, to a polymerization powder, to an adhesive bonding formulation comprising the polymer dispersion of the invention, and to the use of the formulation of the invention as an adhesive.
