NONIONICALLY AND PARTIALLY ANIONICALLY STABILIZED WATER-DISPERSIBLE POLYURETHANE/ACRYLIC GRAFT COPOLYMERS

摘要

Water-dilutable polyurethane/acrylic copolymers whichmay be either completely nonionically stabilized orpartically nonionically and partically anionicallystabilized comprise the reaction product of anethylenically terminated polyurethane macromonomercontaining poly(oxyalklyene) segments and one or moreethylencially unsaturated monomers selected from acrylicacid, methacruylic acid, fumaric acid, styrene,vintyltoluene, and alkyl and hydroxyalkyl esters ofacrylic, methacrylic, and furamic acids. The copolymersare useful as principal resins and as pigment grind resinsin water-borne automotive base coat paint formulations.
