1,4-α-D-Polyglucan-based thermoplastic mixture, process for the preparation and use thereof n The present invention relates to a thermoplastic mixture based on biopolymers obtainable by preparing and mixing n (A) 100 parts by weight of a biocatalytically produced 1,4-α-D-polyglucans, n (B) up to 400 parts by weight of a melt-processable polymeric material different from (A), n (C) water in an amount sufficient for plastification of the mixture, n (D) at least one plasticizer in an amount of 10 parts by weight up to half the total of the parts by weight of (A) and (B), and n (E) where appropriate up to ((A)+(B)) parts by weight of other conventional additives, where the water content of components (A) and (B) has been corrected to zero by calculation n where the plastification takes place with introduction of thermal and mechanical energy, to the use of the mixture for producing essentially biodegradable moldings and sheets, and to a process for preparing the mixture. |
