  • Polymer compositions
    Publication number: 20060024263
    Abstract: There is disclosed polymers and aqueous dispersions of them, the polymers containing specific copolymers which comprise at least four different ethylenically unsaturated monomers (such as 2-ethylhexyl acrylate, ethyl acrylate, methyl acrylate and styrene, and optionally (meth)acrylic acid, ethyl imidazolidone methacrylate, n-butyl acrylate n-dodecyl methacrylate and/or methyl methacrylate). Also described is production of said polymers and dispersions by emulsion polymerization and their use as adhesives, for example as pressure sensitive adhesives on polymeric film.

  • Pressure-sensitive adhesives and self-adhesive films using said adhesives
    Patent number: 6214931
    Abstract: Pressure sensitive adhesives comprised of an aqueous dispersion of a copolymer of acrylic esters obtained in the presence of a crosslinking monomer carrying a functional group are set forth, said copolymer having a glass transition temperature which does not exceed 0° C. The crosslinking monomer is methacrylic anhydride. The resulting adhesive displays improved adhesion and cohesion properties.
