Biostable, segmented aliphatic polyurethanes and processes for their preparation |
| abstract |
Highly stable, segmented, aliphatic polyurethanes particular processes for preparing them are disclosed. The segmented polyurethanes of this invention are substantially free of ester and ether linkages and are found to be particularly hydrolytically and oxidatively stable. The polyurethanes of this invention are prepared by a particular two stage process involving the formation of a prepolymer and subsequent reaction with simultaneously or sequentially added diisocyanate and diol monomers. |
