    Abstract: A method for producing an aqueous polymer dispersion with solids content of greater than 60 percent by weight is described. A dispersed polymer is thus produced by radical emulsion polymerisation in the presence of a polymeric protective colloid. The polymer is formed from at least 80 percent by weight (meth)acrylate ester monomers and the polymeric protective colloid is formed from acid monomers and at least 10 percent by weight (meth)acrylate ester monomers and the total of (meth)acrylate ester monomers and acid monomers of the protective colloid is at least 80 percent by weight. The emulsion is polymerised in the monomer feed method, wherein the starting speed of the monomer feed is lower than the end speed. The aqueous polymer dispersions can be used as adhesives, among other things.

    Abstract: The invention relates to a contact adhesive dispersion, containing a polymer P1 which can be dispersed in water and is formed by emulsion polymerization. The polymer P1 is formed from a monomer mixture, containing (a) at least 40% by weight C4 to C20 alkyl(meth)acrylates which have a glass transition temperature of -30ºC or less if they are polymerized as homopolymers, (b) at least 0.05% by weight (meth)acrylate monomers containing a substituent of the formula, where X denotes CH
    2 , O, NH or NR and R denotes a C1 to C4 alkyl group, and (c) at least 0.1% by weight acid monomers. The polymer P1 is produced by means of polymerization in at least two stages, wherein the glass transition temperature of a polymer made of monomers of the first stage is at least 20ºC lower than the glass transition temperature of a polymer made of monomers of a later, second stage.

    Abstract: The invention relates to a method for the production of an aqueous polymer dispersion, a copolymer CP, at least two different monomers M1, and M2, by radical polymerization of an aqueous emulsion of the monomers M in the presence of at least one initiator, whereby at least 80 % the monomers M and at least 75 % of the initiator of the polymerization reaction are continuously added during the polymerization process. The invention is characterised by multiple or continuous variations of the rate at which the polymerization initiator is added. The invention also relates to polymer dispersions which can be obtained according to said method, polymer powders produced therefrom and the use of such dispersions or polymer powders in the production of pressure-sensitive materials.
