ABSTRACT:
This invention relates to terpolymers which are capable of forming hydrogels having very good compatibility with living tissues and may be used as substitutes for damaged tissues, as in the form of implants and various prostheses. The terpolymers are comprised of an oligourethane having an average molecular weight from 1200 to 3000, 2-hydroxyethyl(meth)acrylate or 2-hydroxypropyl(meth)acrylate, and N-vinylpyrrolidone.
