Processes for the preparation of biocompatible polyurethanes are described, in which cycloaliphatic diisocyanates and macrodiols are reacted to give a preadduct. The preadduct chain is extended by means of a mixture of a low-molecular-weight diol and a macrodiol. …<??>The resultant polyurethanes have high stability in the animal and human body and are suitable, inter alia, for the production of catheters, blood pumps, heart valves and biocompatible lacquers. |
