Abstract

A resin composition including a lignin skeleton capable of producing a heat-resistant molded article and being decomposed under relatively mild conditions. The resin composition contains a lignin skeleton including, as a base component, a phenolated lignin or a derivative thereof that contains a reactive monomer group, the phenolated lignin containing a phenol-containing monomer represented by the following general formula (I): wherein R1 to R5 are each independently a monovalent group selected from H, OH, a C1 to C6 alkyl group, a C1 to C6 alkoxy group, and a C6 to C10 aryl group, or adjacent substituents among R1 to R5 form a substituted or unsubstituted aromatic ring together, at least one of R1 and R2 is a hydroxyl group, and R6 is OCH3 or H; a molded article thereof, as well as a recycling method for a molded article formed in a mold formed of the resin composition.
