    摘要： The present invention relates to a process for preparing an aqueous polymer dispersion comprising dispersed polymer particles of at least one addition polymer A1 obtainable by semicontinuous free-radical emulsion polymerization of ethylenically unsaturated monomers in the presence of an addition polymer A2 synthesized from from 50 to 99.5% by weight of at least one ethylenically unsaturated monocarboxylic and/or dicarboxylic acid, from 0.5 to 50% by weight of at least one ethylenically unsaturated compound selected from the esters of ethylenically unsaturated monocarboxylic acids and the monoesters and diesters of ethylenically unsaturated dicarboxylic acids with an amine containing at least one hydroxyl group, and up to 20% by weight of at least one further monomer, which comprises supplying a) at least one portion of the ethylenically unsaturated monomers, b) a portion of the water, c) at least one portion of the polymer A2, and, if desired d) portions or entireties of further auxiliaries to the polymerization vessel together, without an emulsion being formed, through a feed line.

    摘要： The invention relates to a process for preparing an aqueous polymer dispersion comprising an emulsion polymer a polymer composed of at least 5% by weight of an ethylenically unsaturated monocarboxylic acid, dicarboxylic acid or dicarboxylic anhydride (acid polymer SP for short), and an alkoxysilane of the formula SiR1R2R3R4 in which the groups R1 to R4 independently of one another are each an organic radical with the proviso that at least one of the groups is an alkoxy group, which comprises preparing said emulsion polymer by emulsion polymerization in the presence of at least some of the alkoxysilane.
