Title:
LIGNIN DERIVATIVE, LIGNIN RESIN COMPOSITION, RUBBER COMPOSITION, AND MOLDING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2016/039213
Kind Code:
A1
Abstract:
Provided is a lignin derivative extracted from biomass, the lignin derivative being for reinforcing rubbers or for use in molding materials. The lignin derivative is characterized by having a number-average molecular weight of 300-2,000 and comprising components soluble in polar organic solvents, in an amount of 80 mass% or larger. Incorporation of such lignin derivative makes it possible to obtain a lignin resin composition, rubber composition, or molding material which is excellent in terms of low-hysteresis-loss characteristics, elastic modulus, or tensile property. By using heat-fusible components as the soluble components, said properties of the lignin resin composition, rubber composition, or molding material can be rendered even better.
