Document Type and Number:
Japanese Patent JP5544615
Kind Code:
B2
Abstract:
To provide a thermoreversible cured product permitting material recycle from lignin as a raw material which is a main constituent of a plant in order to effectively utilize biomass resources.
The thermoreversibly reactive polymer compound comprises a polyester compound, obtained by adding a compound bearing a furan ring and an epoxy group to a carboxy group of a polyester compound obtained by a reaction of a lignin substance dissolved in a polyol with a carboxy compound, and a polyvalent maleimide compound, and can be not only hardened but also softened by a reversible Diels-Alder reaction.
