Abstract

Described are polyurethane-vinyl hybrid polymers, methods of making them and their use. The hybrid polymers are made from an anionic polyurethane and a polymerizable vinyl compound, wherein the polymerizable vinyl compound is selected from methylene malonates, methylene beta-ketoesters and methylene beta-diketones. The hybrid polymers can be used as binder in structural adhesives, as binder in pressure-sensitive adhesives, as binder in laminating adhesives, as binder in contact adhesives, as binder in ink, as binder in paints, as binder in coatings, as binder for fiber bonding, as binder for particle bonding or as binder in high cohesion adhesive tapes.
