Hydrophilic polyurethanes containing (meth)acryloyl groups, their use as reactive emulsifiers for radically curable synthetic resins, water- dispersible mixture of radically curable synthetic resins and an aqueous coating composition based on this mixture

摘要

A polyurethane is disclosed having improved properties as a reactive emulsifier for radically-curable synthetic resins. The polyurethane is obtained by the reaction of a) a polyisocyanate component; b) an alcohol component; and c) a polyethylene glycol component. The reactive emulsifiers are useful in aqueous coating compositions.
