The present application discloses cellulose ester compositions that are plasticizer free that can be processed at higher temperatures with reduced degradation. The cellulose ester compositions disclosed are useful for the preparation of articles, for example eyeglass frames, automotive parts, and toys.

Thermally stable cellulose ester compositions and articles made using these compositions

A cellulose ester composition is provided comprising at least one cellulose ester and at least one impact modifier and optionally at least one plasticizer. Processes for producing the cellulose ester compositions as well as articles made using these compositions, such as eyeglass frames, automotive parts, and toys are also provided.

Cellulose ester and impact modifier compositions and articles made using these compositions

A cellulose ester composition is provided comprising at least one cellulose ester, at least one polymeric aliphatic polyester, at least one impact modifier, and at least one monomeric plasticizer. Processes for producing the cellulose ester compositions as well as articles made using these compositions, such as eyeglass or sunglass frames and/or lenses, are also provided.

Cellulose ester and polymeric aliphatic polyester compositions and articles

A shaped article comprising a polymer-based resin derived from cellulose, wherein the polymer-based resin has an HDT of at least 95&#xb0; C., a bio-derived content of at least 20 wt %, a notched izod impact strength of greater than 80 J/m and at least one of the following properties chosen from: flexural modulus of greater than 1900 MPa; a spiral flow length or at least 3.0 cm; a flex creep deflection of less than 12 mm; a transmission of at least 70%; a &#x394;E value of less than 25; or an L* color of at least 85.

Polymer-based resin compositions derived from cellulose and articles made using these compositions

A cellulose ester composition is provided comprising at least one cellulose ester and at least one polymeric aliphatic polyester (PAP), and optionally at least one impact modifier and/or at least one monomeric plasticizer. Processes for producing the cellulose ester compositions as well as articles made using these compositions are also provided.

A cellulose ester composition is provided comprising at least one cellulose ester and at least one ethylene vinyl acetate copolymer and optionally at least one plasticizer. Processes for producing the cellulose ester compositions as well as articles made using these compositions, such as eyeglass frames, automotive parts, and toys are also provided.

Cellulose ester and ethylene vinyl acetate compositions and articles made using these compositions

An injection molded article comprising a thin-walled body portion formed from a polymer-based resin derived from cellulose, wherein the thin-walled body portion comprises:
