Abstract

See full text

The cellulose acetate resin composition may include: a cellulose acetate having a total degree of acetyl substitution of 1.9 or greater and 2.6 or less; and a plasticizer. The cellulose acetate may have a number average molecular weight of 45000 or greater and a weight average molecular weight of 70000 or greater. The plasticizer may be selected from (1) an ether-based plasticizer in which at least one terminal hydroxyl group of a polyalkylene glycol is etherified, and (2) an ester-based plasticizer in which at least one terminal hydroxyl group of a polyalkylene glycol is esterified. The polyalkylene glycol in the ether-based plasticizer (1) and the ester-based plasticizer (2) may have a degree of polymerization of 3 or greater and less than 10. The plasticizer may not include an aromatic ring in the terminal group.
