ABSTRACT:
A process for the production of a homogeneous, thermoplastically processible melt. The process includes a. introduction of chemically modified starch into an intake zone of an extruder and conveyance thereof to a receiving zone, b. addition of a prehomogenized liquid mixture of plasticizer, emulsifier, and additives, followed by mixing and further conveyance of the starch liquid mixture through the receiving zone at elevated temperature, c. destructurization of the modified starch without adding any water and conveyance of the starch and mixture at elevated temperature to form a homogeneous, thermoplastically processible melt, d. degassing of the melt at elevated temperature and under reduced pressure, and e. extrusion thereof through a die at elevated temperature and pressure.
