Abstract

In the manufacture of thermoplastically processable starch, an additive is essentially mixed with native or natural starch and the mixture is caused to melt by the application of heat and mechanical energy. The additive is a substance which lowers the melting point of the starch so that the melting point of the starch together with this additive lies below the decomposition temperature of the starch while, in addition, the additive has a solubility parameter of over 15 cal<1/2>cm<-3/2>. Once the starch-additive mixture has melted, the molten substance is mixed until it is at least virtually homogenous. In the melting range of the starch-additive mixture, the vapour pressure of the additive should be lower than 1 bar.
