Abstract

A biodegradable polymer mixture is proposed which essentially comprises starch and at least one hydrophobic polymer. The hydrophobic polymer should be at least substantially biodegradable and thermoplastically processible, and the mixture with the starch should contain a polymeric phase promoter or a macromolecular dispersant, so that the starch is present in the mixture as the disperse phase with the hydrophobic polymer as the continuous phase, and the phase promoter or the dispersant is responsible for the molecular coupling of the two phases. The starch used is preferably thermoplastic starch prepared by means of sorbitol or glycerol essentially in the absence of water. The preparation of the biodegradable polymer mixture should likewise take place essentially in the absence of water.
