1. A method comprising:
- contacting at least one isocyanate-terminated component with a dilute solution comprising at least one amine at a concentration of from about 0.01 weight percent to about 0.5 weight percent of the solution; and
allowing the at least one isocyanate-terminated component and the at least one amine to react in situ thereby forming a biocompatible composition.
