Abstract
Graft copolymers of well-defined structure composed of a 2,3-dihydroxypropyl methacrylate backbone and uniform molecular weight polystyrene branches were prepared by the macromonomer method and studied for their application as hydrogels utilizing their microdomain structure. Film specimens prepared by solution casting of the graft copolymer swelled immediately in water to form stable hydrogels which were characterized by measuring the equilibrium degree of swelling and the oxygen permeability in water. Swelling behavior of the hydrogel was also characterized by the small angle X-ray scattering (SAXS) measurement. It is clearly shown that the microphase separated structure of the graft copolymers is considerably regular and the swelling behavior and the oxygen permeability coefficient of hydrogels can be well-controlled by both the architecture of preformed graft copolymers and the microdomain structure in the cast specimens.
