  • Waterborne hybrid polymer dispersion
    Patent number: 9944743
    Abstract: The process for the manufacture of an auto-oxidatively cross-linking hybrid polymer, in particular an aqueous hybrid polymer dispersion, comprises the step of reacting in a mini-emulsion process one or more ethylenically unsaturated monomers to form an addition polymer in the presence of a modified auto-oxidatively crosslinkable (AOC) polymer which has been modified with terminal unsaturated groups of the formula —C(R1)?CH2 wherein R1 is hydrogen, alkyl or aryl and wherein the AOC polymer is a hydrophobic polymer having an acid number between 5 to 30. The resulting aqueous hybrid polymer dispersion can be used for the manufacture of coating compositions, ink compositions or adhesives and coating compositions comprising the hybrid polymer dispersion as a binder.

  • WATERBORNE HYBRID POLYMER DISPERSION
    Publication number: 20130018127
    Abstract: The invention relates to a process for the manufacture of an auto-oxidatively cross-linking hybrid polymer, in particular an aqueous hybrid polymer dispersion, comprising the step of reacting in a mini-emulsion process one or more ethylenically unsaturated monomers to form an addition polymer (also referred to as a vinyl polymer) in the presence of a modified auto-oxidatively crosslinkable (AOC) polymer which has been modified with terminal unsaturated groups of the formula C(R1)?CH2 wherein R1 can be hydrogen, alkyl or aryl and wherein the modified AOC polymer is a hydrophobic polymer having an acid number between 5 to 30.
