Abstract: A polymer which containsfrom 50 to 99.98% by weight of a C1-C12 alkyl (meth)acrylate a),from 0.02 to 10% by weight of a vinylaromatic compound b),from 0 to 10% by weight of an ethylenically unsaturated acid or of an ethylenically unsaturated acid anhydride c), andfrom 0 to 40% by weight of further monomers d), the percentages by weight being based on the polymer and the polymer being obtainable by polymerizing the monomers a) to d) in at least two stages which differ in their content of vinylaromatic compounds in such a way that the content of vinylaromatic compounds in the vinylaromatics-rich stage is at least 5 times as great as in the low-vinylaromatics stage.

Abstract: 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.

Abstract: A polymer which is composed offrom 50 to 99.98% by weight of a C1-C12 alkyl (meth)acrylate a),from 0.02 to 1.8% by weight of a vinyl-aromatic compound b),from 0 to 10% by weight of an ethylenically unsaturated acid or an ethylenically unsaturated acid anhydride c), andfrom 0 to 40% by weight of other monomers d), the percentages by weight being based on the polymer.
