摘要
a method for producing a modified lignin, including reacting one or more types of a second generation ethanol fermentation residue, and a second generation ethanol saccharification residue, with a phenol compound, a modified lignin having a ratio ( (2h + g) / s) of a total of two times a relative existence ratio h (%) of a type h skeleton, and a relative existence ratio g (%) of a type g skeleton with respect to a proportion relative existence s (%) of a type s skeleton, obtained from integrated values measured by 31p-nmr, of 2.5 or more, and a proportion of existence of an aliphatic hydroxy group obtained by the same method of less than 20% , and a resin composition material containing modified lignin.
