摘要:
The invention relates to a specific composition comprising A) isocyanate-functional prepolymers obtainable by reaction of A1) aliphatic diisocyanates with A2) di- to hexa-functional polyalkylene oxides having an ethylene oxide content of 50 to 100 mol %, based on the total amount of the oxyalkylene groups present, B) an aqueous polyurethane suspension, an aqueous polyacrylate suspension or aqueous silica sols, especially for production of hydrophilic, aliphatic polyurethane foams. The invention further provides a process for producing a hydrophilic, aliphatic polyurethane foam, based on the inventive composition, a polyurethane foam obtainable by the process and a wound dressing comprising the polyurethane foam.
