Polyurethane foams (PU) were prepared combining natural polysaccharides with polyester polyols and an aliphatic diisocyanate. Two classes of PU foams were studied: the first one was prepared by using starch as one of the components of the polyol mixture, while the second class was prepared by adding starch as filler to a reactive mixture containing sucrose in the polyol composition. Influence of chemical composition on mechanical, thermal and morphological properties were investigated. Moreover, biodegradation tests were performed on selected foams.
