    摘要: Polyvinyl-alcohol-stabilized redispersible powders which have plasticizing properties are obtained by drying polyvinyl-alcohol-stabilized aqueous dispersions of polymers of one or more monomers from the group of vinyl esters of optionally branched C1-18 alkylcarboxylic acids, (meth)acrylic esters of optionally branched C1-15 alcohols, dienes, olefins, vinylaromatics and vinylhalides, in the presence of a copolymer formed from a) one or more monomers from the group of ethylenically unsaturated monocarboxylic acids, ethylenically unsaturated dicarboxylic acids and their anhydrides, each having 4 to 8 carbon atoms, and salts thereof, b) one or more ethylenically unsaturated compounds containing sulfonic, sulfuric, and/or phosphonic acid groups, and salts thereof, and c) one or more monomers from the group consisting of vinyl esters of optionally branched C1-18 alkylcarboxylic acids and (meth)acrylic esters of optionally branched C1-15 alcohols.

    摘要: The invention provides mixed aromatic vinyl-1,3-diene polymers stabilized by a protective colloid and present in the form of aqueous polymer dispersions or polymer powders redispersible in water as adhesives for porous substrates. The polymer dispersions and the polymer powders are obtained by emulsion polymerization of a mixture containing: a) 20 to 80 percent by weight of one or more vinylaromatics; b) 19.9 to 79.9 percent by weight of one or more 1,3-dienes; c) 0.1 to 15 percent by weight of one or more comonomers from the group consisting of N-methylolacrylamide, N-methylolmethacrylamide and the N-(alkoxymethyl)-acrylamides and N-(alkoxymethyl)-methacrylamides with a C1 to C6-alkyl radical. The sum of the above percentages adds up to 100% by weight. Emulsion polymerization is carried out in the presence of one or more protective colloids and without emulsifiers, optionally followed by drying of the resulting aqueous polymer dispersion.
