    摘要: A description is given of a pressure-sensitive adhesive dispersion comprising a water-dispersed polymer P1 formed by emulsion polymerization. The polymer P1 is formed from a monomer mixture comprising (a) at least 40% by weight of C4 to C20 alkyl (meth)acrylates which when polymerized as homopolymers have a glass transition temperature of −30° C. or less, (b) at least 0.05% by weight of (meth)acrylate monomers having a substituent of the formula where X is CH2, O, NH or NR and R is a C1 to C4 alkyl group, (c) at least 0.1% by weight of acid monomers. The polymer P1 is prepared by polymerization in at least 2 stages, the glass transition temperature of a polymer from monomers of the first stage being lower by at least 20° C. than the glass transition temperature of a polymer from monomers of a later, second stage.

    摘要: Described is a polymer film with multiphase film morphology. The polymer film, within a layer, has regions of a first polymer and regions of a second polymer, and is prepared from an aqueous polymer dispersion, comprising the two polymers in dispersed form and a tackifier. The glass transition temperature of the second polymer is greater than that of the first polymer and less than 20° C. The concentration of the tackifier in the polymer film is greater in the regions of the first polymer than in the regions of the second polymer. Described also are polymer dispersions for producing polymer films with multiphase film morphology, and also applications as adhesive, coating or sealant, as for example for producing self-adhesive paper labels.
