  • Publication number: 20160215143
    Abstract: Disclosed is a resin composition containing lignin and a phenol resin, the lignin being one resulting from separation of a cellulose component and a hemicellulose component from a decomposition product obtained by subjecting a plant raw material to a decomposition treatment, and the lignin and the phenol resin being mixed in a solvent. It is possible to provide a resin composition capable of being melt kneaded at low temperatures and having excellent processability and moldability, a production method for the same, and a molded product using the same.
