LIGNIN RESIN COMPOSITION, RESIN MOLDED ARTICLE, AND MOLDING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a lignin derivative having high reactivity and an excellent hot-melt property.;SOLUTION: A resin composition comprising a lignin derivative is provided, in which a lignin derivative includes a phenolic structure in the structure thereof, and a content of sulfuric acid in the resin composition is less than 2 mass%. The lignin derivative is a lignin obtained by decomposing biomass at high temperature and high pressure in the presence of a mixture solvent comprising water and a phenolic structural material. The phenolic structure included in the lignin derivative structure is obtained by addition of a phenolic structure into the lignin derivative; and the lignin derivative has a number average molecular weight of 300 to 3000.;COPYRIGHT: (C)2015,JPO&INPIT
