1,4-.alpha.-d-polyglucan-based thermoplastic mixture, process for the p reparation and use thereof

Abstract From the Canadian patent

The present invention relates to a biopolymer-containing thermoplastic mixture which is obtained by preparing and mixing: (A) 100 parts by weight of a 1,4-.alpha.-D-polyglucane produced by a bio-catalytic method; (B) up to 400 parts by weight of a polymeric material other than (A) and capable of undergoing a thermoplastic process; (C) an amount of water sufficient for plastifying the mixture; (D) at least one plasticizer in amount ranging from 10 parts by weight to the half the summed parts by weight of (A) and (B); and (E) optional other common additives in an amount not exceeding ((A) + (B)) parts by weight. The water content of constituents (A) and (B) is reduced to 0 using computer …
