Title:
MANUFACTURING METHOD FOR MODIFIED LIGNIN AND MODIFIED POLYPHENOL, AND MODIFIED LIGNIN-INCLUDING RESIN COMPOSITION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/031609
Kind Code:
A1
Abstract:
A manufacturing method for a modified lignin and a modified polyphenol, and a modified lignin-including resin composition material, wherein the ratio [(2H+G)/S] of the sum of two times the relative abundance H (%) of an H-type skeleton and the relative abundance G (%) of a G-type skeleton to the relative abundance S (%) of an S-type skeleton, as calculated from integrated values measured by 31P-NMR, is 2.5 or greater, and the abundance of an aliphatic hydroxyl group as measured by the same technique is less than 20%.
