Abstract: A resin composition for molding having excellent heat resistance, hardness, cost-effectiveness and biodegradability is provided by using amorphous resin material components extracted from plant-derived wood. The resin composition includes a first resin including a hemicellulose or a hemicellulose derivative and a second resin including polymethylmethacrylate (PMMA, acrylic), polycarbonate (PC), cyclo olefin polymer (COP), cyclo olefin copolymer (COC), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), or polystyrene (PS) and has excellent injection moldability.

Abstract: A resin composition for molding having excellent heat resistance, hardness, cost-effectiveness, and biodegradability is provided by using an amorphous resin material component extracted from plant-derived wood. The resin composition is a hemicellulose monomer obtained by applying a methacrylation reaction or acrylation reaction to a hemicellulose or hemicellulose derivative and has a molecular structure in which a methacrylic group or acryloyl group is bonded to the hemicellulose or hemicellulose derivative. This hemicellulose monomer has excellent injection moldability.
