Abstract: Cellulose acetate propionate is a cellulose ester wherein hydroxyl groups of cellulose are substituted with acetyl and propionyl. Cellulose acetate propionate of the present invention has an amorphous index (Am) of not more than 0.4. Cellulose acetate propionate has a degree of acetyl substitution (DSac) and a degree of propionyl substitution (DSpr), which preferably satisfy the formulas (I) to (III), and more preferably satisfy the formulas (I) to (IV). The present invention also provides a solution of cellulose acetate propionate and a cellulose acetate propionate film.

Abstract: Cellulose acetate which can provide moldings improved in the properties, particularly film strength and pliability. The cellulose acetate has an average degree of acetylation of not less than 59 %, a viscosity-average degree of polymerization (DP) of not less than 290, and a viscosity ( eta ), as measured in the form of a concentrated solution thereof by the falling-ball method, satisfying a requirement for the relationship with the viscosity-average degree of polymerization (DP) represented by the following formula (1): 2.814 x 1n(DP) - 11.753
