  • Publication number: 20200056011
    Abstract: 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 %.
