Title:

CELLULOSE ACETATE EXCELLENT IN MOLDABILITY AND METHOD FOR PRODUCING THE SAME

Document Type and Number:

Japanese Patent JP2007009221

Kind Code:

A

Abstract:

To provide a film comprising cellulose acetate substantially low in crystallinity, excellent in moldability and having low polymerization degree.

The film comprises cellulose acetate having average acetylation degree of ≥58.0%, a viscosity-average polymerization degree (DP) of ≥200 but ≤290, and concentrated solution viscosity (η) represented by formula (1), measured by falling-ball viscometry and based on the viscosity-average polymerization degree (DP).
