In this study, from the viewpoint of biodegradable polymers and waste disposal, polyurethane (PU) foams and films containing sericin were prepared from sericin and diphenylmethane diisocyanate. Polyethylene glycol and polypropylene glycol were used as a part of the polyol. Mechanical and thermal properties of PU's containing sericin were measured by tensile test and thermal analysis. Sericin could be used as a polyol of PU's and the strength and the glass transition temperature of PU films containing sericin increased with increasing sericin content. The stength of PU foams depended strongly on their apparent density.
