Abstract:
A cellulose resin wherein a hydrogen atom of a hydroxy group of cellulose is 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 an acyl group (propionyl group) having 3 carbon atoms, the degree of substitution with the long-chain component (DSLo) and the degree of substitution with the short-chain component (DSSh) satisfy the following conditional expressions (1) and (2): DSLo+DSSh≥2.1 (1) 4≤DSSh/DSLo≤12 (2), the Izod impact strength is 5.0 kJ/m2 or more, and the MFR (melt flow rate at 200° C. and under a load of 5 kg) is 10 g/10 min or more.
