CELLULOSE-BASED RESIN, MOLDING MATERIAL, MOLDED BODY, AND METHOD FOR MANUFACTURING CELLULOSE-BASED RESIN

摘要

Provided is a cellulose-based resin in which hydrogen atoms in hydroxyl groups of cellulose are substituted with a long-chain component, which is a linear saturated aliphatic acyl group having 14 or more carbon atoms, and a short-chain component, which is a C3 acyl group (propionyl group), wherein the degree (DS_Lo) of substitution by the long-chain component and the degree (DS_Sh) of substitution by the short-chain component satisfy conditional expressions (1) and (2) below, the Izod impact strength is at least 5.0 kJ/m², and the MFR (melt flow rate at 200°C and a load of 5 kg) is at least 10 g per 10 minutes. (1) DS_Lo+DS_Sh≥2.1, (2) 4≤DS_Sh/DS_Lo≤12.
