    摘要: A process is disclosed for producing thermoplastic starch based on renewable raw materials and, if required, for further processing it into a granulate. A low viscosity starch is modified under a low shearing stress during the extrusion process and leaves the extruder with an increased viscosity in the form of a strip, threads or in other geometrical shapes. The advantages of the invention mainly lie in the improved quality of the starch products, the preservation of the mechanical parts of the extruder installation and the increase of the nominal output of the extruder.

    摘要: A biologically degradable polymer mixture containing at least one biopolymer made from renewable raw materials and a polymer selected from the following materials: an aromatic polyester; a polyester-copolymer with both aliphatic and aromatic blocks; a polyesteramide; a polyglycol; a polyester urethane; and/or mixtures of these components. The preferred renewable raw material is starch, more preferably native starch, most preferably native starch that has been predried.
