Abstract
Copolymers between polylactic acid and polyethylene glycol, also alganic acid and polyethylene glycol were synthesized and diisocynate (MDI) were prepared and characterized. Swelling behaviors and loss of weight of these polyurethanes were studied by immersion of the gels in various buffer solutions. Particularly the polyurethane foam showed the highest EWC (equilibrium water constant) in time-dependent and pH-dependent swelling.
