  • Degradable polyurethane foams
    Patent number: 8318820
    Abstract: A method of synthesizing of a biocompatible and biodegradable polyurethane foam includes the steps of: mixing at least one biocompatible polyol, water, at least one stabilizer, and at least one cell opener, to form a resin mix; contacting the resin mix with at least one polyisocyanate to form a reactive liquid mixture; and reacting the reactive liquid mixture form a polyurethane foam. The polyurethane foam is preferably biodegradable within a living organism to biocompatible degradation products. At least one biologically active molecule having at least one active hydrogen can be added to form the resin mix.
