Title:
【発明の名称】生分解性成形品を製造するためのデンプンを主原料とする熱可塑性混合物
Document Type and Number:
Japanese Patent JP2001509525
Kind Code:
A
Abstract:
The invention relates to a thermoplastic mixture with a starch base, for producing biodegradable moulded bodies with improved properties, preferably improved mechanical properties. The inventive thermoplastic mixture can be obtained by providing and mixing; A) 100 weight parts of any native, chemically modified, fermentative starch which is recombinant and/or produced by biotransformation and corrected to a water content of zero per cent by calculation, and/or derivatives of said starches, B) optionally up to 100 weight parts of a physiologically harmless, biodegradable, thermoplastically processable polymeric material which is different from A), C) 1 to 100 weight parts of water, D) at least one plasticiser in a quantity of between 10 weight parts to half of the sum of the weight parts of A) and B), E) at least one phosphate, preferably a phosphoric acid salt, in a quantity of between 0.01 weight parts and (A)+B))/10 weight parts, and F) optionally, up to (A)+B)) weight parts of other usual additives. At least the mixing of constituents A and A) is carried out with the introduction of heat and mechanical energy, preferably at a high temperature with shearing forces being applied to the thermoplastic mixture simultaneously.
