    摘要: Described is a polymer dispersion comprising in an aqueous medium (a) dispersed particles of a polymer containing more than from 5 to 20% by weight of &agr;,&bgr;-ethylenically unsaturated mono- or dicarboxylic acid, (b) a dissolved polymer containing from 60 to 100% by weight of &agr;,&bgr;-ethylenically unsaturated mono- or dicarboxylic acid, and (c) an alkoxylated long-chain amine. Heat-curable compositions are obtained by adding polyfunctional alcohols and, optionally, reaction accelerant. The polymer dispersions and the heat-curable compositions are suitable for use as binders for textile sheetlike structures and for moldings.

    摘要: Readily filterable and deodorizable aqueous dispersions of pressure-sensitive adhesive, especially for self-adhesive labels, having solids contents of more than 65%, can be prepared with readily reproducible properties by copolymerizing esters of acrylic and/or methacrylic acid in the presence of less than 50 ppm of inhibitor and, preferably, in the presence of from 0.01 to 5% by weight of reducing agent by a special emulsion technique. The highly concentrated pressure-sensitive adhesive dispersion, subsequently deodorized with steam, is free from coagulum and seediness.
