  • 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 %.

  • Patent number: 10364345
    Abstract: An monolithic interlayer with high stiffness and when laminated into a glass panel, the glass panel exhibits good clarity, while maintaining the processability of a polyvinyl acetal, such as polyvinyl butyral resin used to make the monolithic interlayer. The monolithic interlayer comprising a polymer blend of: (A) polyvinyl acetal (e.g. PVB); and (B) one or more cellulose esters. The polymer blend increases the structural strength to the monolithic interlayer by increasing the E? modulus of the monolithic interlayer while optionally maintaining good optical clarity.
