Biologically degradable composition, this shaped article and process for the preparation of biologically degradable material

摘要

a biodegradable plastic or a similar ausgeformter object is formed from a composition of the 100 parts of cellulose fibres with a length of 3 mm or less and a diameter of 50 m or less, 10 to 600 parts of a thermoplastic resin. d 2 to 100 parts of chitosan contains.a mixture, (a) an aqueous solution of an acid salt of chitosan, (b) an aqueous dispersion or solution of a thermoplastic resin and (c) containing fine cellulose, is dried and formed to an object, the biodegradable.
