Title:
LIGNIN RESIN COMPOSITION, CURED OBJECT, AND MOLDED OBJECT
Document Type and Number:
WIPO Patent Application WO/2016/080469
Kind Code:
A1
Abstract:
Provided is a lignin resin composition which comprises a lignin derivative having a weight-average molecular weight of 500-4,000 and a phenolic novolak resin having a weight-average molecular weight of 1,000-3,000, the content of the lignin derivative being not higher than the content of the phenolic novolak resin. In particular, lignin-resin-composition cured objects (molded objects) obtained by melt-mixing the lignin resin composition, adding hexamethylenetetramine to this mixture, and heating the resultant mixture have high bending strength. The lignin resin composition is utilizable as a thermosetting resin that is a phenolic-resin substitute.
