Abstract

Thermoplastically processable starch and procedures for the preparation thereof. With the aim of preparing thermoplastically processable starch, an additive material is added to an essentially native or natural starch, and the mixture is turned into a molten mass by the application of heat and mechanical energy. The additive material consists of a substance that reduces the melting point of the starch, in such a way that the melting point of the starch together with this additive material is below the decomposition temperature of the starch, and furthermore the additive material has a solubility parameter greater than 15 cal1/2cm-3/2. After melting the mixture of starch and additive material, the molten mass is mixed until it is at least almost homogeneous. The vapour pressure of the additive material must be less than 1 bar in the melting range of the mixture of starch and additive material.
