Title (EN) WATER-DISPERSIBLE UNSATURATED POLYURETHANE
(FR) POLYURETHANNE INSATURE DISPERSIBLE DANS L'EAU
Abstract:
(EN) A water-dispersible unsaturated polyurethane comprising pendant unsaturated alkyl groups, pendant sulphonic acid salt groups and pendant alkoxy polyoxyalkylene groups is described. The sulphonic acid salt groups and alkoxy polyoxyalkylene groups are present in amounts at least sufficient to render the unsaturated polyurethane water dispersible. The unsaturated polyurethane is especially suited for dispersing alkyds in water. Also disclosed is a composite latex comprising an aqueous alkyd dispersion and monoethylenically unsaturated monomers and a pigment dispersion comprising a pigment or pigment paste and the unsaturated polyurethane.
(FR) L'invention concerne un polyuréthanne insaturé dispersible dans l'eau, comprenant des groupes pendants du type alkyle insaturé, des groupes pendants du type sels d'acide sulfonique et des groupes pendants du type alcoxypolyoxyalkylène. Les groupes sels d'acide sulfonique et les groupes alcoxypolyoxyalkylène sont présents en quantités au moins suffisantes pour rendre le polyuréthanne insaturé dispersible dans l'eau. Le polyuréthanne insaturé est particulièrement utile pour disperser des alkydes dans l'eau. On décrit également un latex composite comprenant une dispersion aqueuse d'alkyde et de monomères à insaturation éthylénique et une dispersion de pigment comprenant un pigment ou une pâte de pigment et le polyuréthanne insaturé.
