ABSTRACT:
The invention disclosed is directed to biodegradable hydrophilic polyurethane structures prepared by using an isocyanate capped hydroxyester polyol reactant with large amounts of aqueous reactant. The resultant foam has economy in handling, and upon contact with liquids or body fluids, the foam is highly absorptive while being readily biodegradable after use.
