(METH)ACRYLOYL GROUP-CONTAINING HYDROPHILIC POLYURETHANE,USE THEREOF AS REAVTIVE EMULSIFIER FOR RADICALLY CURABLE SYNTHETIC RESIN,WATER DIDPERSIBLE MIXTURE OF RADICALLY-CURABLE SYNTHETIC RESIN AND AQUEOUS COATING COMPOSITION BASED ON SAID MIXTURE

摘要

Hydrophilic polyurethanes containing (meth)acryloyl groups and ethylene oxide units are prepared by reacting a polyisocyanate component with an alcohol component containing (meth)acryloyl groups and with a polyethylene glycol component and are used as reactive emulsifiers for densely water-dispersible synthetic resins which can be cured by means of free radicals. The water-dispersible mixture comprises hydrophobic polyurethanes containing (meth)acryloyl groups and hydrophilic polyurethanes of this type and is used as a binder-containing coating composition.
