Definitions

  • the present invention refers to a waterbome homo or copolymer dispersion comprising at least one alkenyl functional dendritic polymer being physically admixed into a homo or copolymer obtained by homo or copolymerisation, such as emulsion homo or copolymerisation, in an aqueous medium.
  • the present invention refers to a process for production of said waterbome homo or copolymer dispersion and to the use of said homo or copolymer dispersion.
  • Emulsion polymerisation is the most important industrial method for manufacture of aqueous dispersion polymers. Emulsion polymerisation is typically performed in an aqueous medium in the presence of a surfactant and a water-soluble initiator and is usually rapidly giving high molecular weight homo or copolymers at high solids content and low dispersion viscosity.
  • the final product is normally an opaque, grey or milky- white dispersion of high molecular weight polymer(s) at a solids content of typically 30-60% in water.
  • Said dispersion typically comprises acrylic, methacrylic and crotonic acid homo and copolymers, methacrylate and acrylate ester homo or copolymers, vinyl acetate homo or copolymers, vinyl and vinylidene chloride homo or copolymers, ethylene homo or copolymers, styrene and butadiene homo or copolymers, acrylamide homo or copolymers, butadiene-acrylonitrile copolymers, styrene- acrolein copolymers and/or where applicable carboxylated versions.
  • aqueous dispersions Traditional applications for such aqueous dispersions are adhesives, binders for fibres and particulate matter, protective and decorative coatings, dipped goods, foam, paper coatings, backings for carpet and upholstery, modifiers for bitumens and concrete and thread and textile modifiers. More recent applications include biomedical applications as protein immobilisers, visual detectors in immunoas- says, as release agents, in electronic applications as photoresists for circuit boards, in batteries, conductive paint, copy machines and as key components in molecular electronic devices.
