Abstract
There is provided a composition comprising covalently linked segments of for example, polycaprolactone and polyethylene glycol that are linked by a cross-linker. Such a composition foams in the presence of a catalyst and a solution containing an oxygen forming chemical like hydrogen peroxide. The foamed composition retains oxygen for delivery to, for example, a wound, where it aids in healing.
