This invention relates to cellulose ester compositions cable of being calendered. The invention also relates to calendered films or sheets comprising the cellulose ester compositions and processes for calendering the cellulose compositions.

Cellulose ester compositions for calendering

The application discloses cellulose ester compositions comprising two or more miscible blends of cellulose ester each comprising a plurality of propionyl substituents having tunable rheology and physical properties not achievable by any one of the cellulose esters alone. These cellulose ester compositions can be further processed, with or without other materials such as plasticizers, flame retardants, and blowing agents, and converted into articles. These cellulose ester compositions have higher modulus and have low to no butyryl/butyric acid content relative to cellulose acetate butyrate ('CAB') cellulose ester compositions made from CABs having a butyryl content of greater than 30 wt %.
