Zusammenfassung:Non-blocking, hemocompatible, thermoplastic, their preparation polyetherurethanes and a method for their preparation from fluorinated polyether glycols, isocyanates, chain extenders and a non-fluorinated polyol. The method includes two steps in which the fluorinated glycol is reacted initially with the diisocyanate to give a prepolymer having terminal isocyanate groups, and the prepolymer is then reacted with the extender and non-fluorinated polyol. Medical devices are fabricated from the fluorinated polyetherurethane.
