The Mater Bi samples made of starch and poly-ε-caprolactone or starch and cellulose derivatives were studied. Enzymatic degradation of Mater Bi samples was investigated by incubating the biomaterial in concentrated trypsin solution. The weight changes, tensile strength and microscopic observations were registered before and after trypsin treatment. Mater Bi composed of thermoplastic starch and poly-ε-caprolactone, having high hydrolytic stability, is also more resistant against attack of trypsin than Mater Bi, composed of starch and cellulose.
