Abstract: A description is given of a one-component pressure-sensitive adhesive composition in the form of an aqueous polymer dispersion comprising at least one pressure-sensitive adhesive polymer which is formed by emulsion polymerization of soft (meth)acrylic ester monomers, methacrylic acid, and optionally further monomers, where the polymerization takes place in the presence of chain transfer agents or styrene. The pressure-sensitive adhesive polymer has a gel content which is based at least partly on a reversible crosslinking via metal salts. The one-component pressure-sensitive adhesive composition can be used for producing adhesive labels, adhesive tapes or adhesive foils.

Abstract: Method of improving shear stability of highly concentrated aqueous adhesive polymer compositions comprising a specific adhesive polymer which has been prepared by emulsion polymerization and which is dispersed in the aqueous adhesive composition. Said method comprises treating the aqueous adhesive polymer composition with at least one anion exchange resin.

Abstract: A description is given of a two-part adhesive product comprising a first composition in the form of an aqueous polymer dispersion comprising at least one adhesive polymer which is formed by emulsion polymerization of soft (meth)acrylic ester monomers, monomers with an acid group, styrene, and optionally further monomers. A second composition comprises a metal salt coagulant which causes instantaneous coagulation of the first composition when contacting the first with the second composition. The two-part adhesive product can be used for adhesively bond-ing foamed substrates
