ABSTRACT:
Water-resistant, thermoplastic starch materials which are processable into environmentally safe, thermoplastically produced products and cast sheets. They consist of starch acyl compounds, obtainable from high amylose starches and their derivatives (being sparingly soluble in water), and of plasticizers (like citric acid ethyl ester, glycerol acetate and lactic acid ester), which have a gelatinizing effect, and preferably, a dissolution property resulting in brilliant transparence and, as can be proved, are biodegradable.
