Document Type and Number:
WIPO Patent Application WO/2023/145958
Kind Code:
A1
Abstract:
The objective of the present invention is to provide: a material that is a cellulose-based composition, is thermoplastic, and does not require the disposal of a solvent or the use of environmentally hazardous substances such as halide-containing substances during the manufacturing process; and a method for producing the same. The thermoplastic composition contains cellulose and a eutectic mixture of monosaccharide and/or disaccharide and hydroxycarboxylic acid. The method for manufacturing a thermoplastic composition comprises: a first step for mixing hydroxycarboxylic acid and monosaccharide and/or disaccharide at a temperature of 150-240 °C; and a second step for mixing the mixture obtained in the first step and cellulose at a temperature of 150-240 °C. In addition, the method for manufacturing a thermoplastic composition comprises a step for mixing cellulose, hydroxycarboxylic acid and monosaccharide and/or disaccharide in an extruder at a temperature of 150-240 °C. The eutectic mixture is preferably a mixture of lactic acid and glucose. In addition, the cellulose content is preferably 0.05-60.0 mass%.
