Process for the production of biocompatible polyurethanes |
| abstract |
The invention relates to biocompatible polyurethanes and their use and their preparation by reacting aliphatic and / or cycloaliphatic and / or cycloaliphatic diisocyanate with a polycarbonate with an average molecular weight of M w = 500 to 6000 and subsequent reaction of the prepolymer thus obtained with a low molecular weight diol or a mixture of low molecular weight diols or a mixture of low molecular weight diols with a macrodiol of the polycarbonate type with an average molecular weight of M w = 500 to 6000, the ratio of NCO groups of the prepolymer to OH groups of the chain extender being 1.01: 1 to 1, Is 05: 1, and then molecular weight fractionation of the polymer obtained to remove the low molecular weight polyurethane content with a mass fraction of 10 to 55 wt .-%. |
