LIGNIN-CONSTITUTING PHENYL PROPANE UNIT α POSITION CHEMICALLY MODIFIED LIGNOCELLULOSE DERIVATIVE, FIBER OR FIBER ASSEMBLY COMPRISING THE SAME, AND COMPOSITION OR FORMED PRODUCT CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide: a chemically modified lignocellulose derivative (α position modified lignocellulose derivatives, lignocellulose with double modifications) that is light weight, has a high strength, has a low linear thermal expansion coefficient, as well as that can exhibit thermoplasticity; a fiber or fiber assembly comprising chemically modified lignocellulose derivative; and a composition as well as a formed product comprising the same.SOLUTION: Provided is a lignocellulose derivative in which α position of a phenyl propane unit constituting lignin is modified with at least one characteristic group selected from the group consisting of an acyloxy group, an oxy group, and a thio group.SELECTED DRAWING: None
