ABSTRACT:
Controlled release membranes are prepared from polyureaurethane polymer derived from prepolymer units at least 75% of which are oxyethylene-based diols or polyols having essentially all of the hydroxyl groups capped with polyisocyanate are disclosed. The membranes are characterized by their biocompatibility and resistance to nonspecific protein adsorption and are particuarly useful for delivery of proteinaceous materials in drug-delivery systems, i.e., wound dressings. Also disclosed are novel biocompatible, protein-nonadsorptive hydrated polymers and the method of producing the same.
