The properties of materials made from the composite of potato starch and ethylene-co-acrylic acid with polyethylene or glycerine added in different amounts were studied. As it has been found, the increasing proportion of easily degradable starch composite increased its solubility in water, methanol and chloroform. Besides, water absorption and resistance to break also increased, but elongation at break and flow coefficient were reduced. The decreasing proportion of polyethylene reduced suitability of the material for commercial use, but in the majority of samples, the reduction was not linear. When polyethylene addition was reduced to 40-50%, the properties of the material obtained were still acceptable.
