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

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 %.

Cellulose ester compositions

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:

An elastomeric composition is provided comprising at least one elastomer, at least one cellulose ester additive, at least one methylene acceptor, at least one methylene donor, and optionally, at least one filler; wherein the cellulose ester additive comprises at least one cellulose ester. The cellulose ester additive can also comprise at least one compatibilizer and/or plasticizer.

Elastomeric compositions comprising cellulose ester additives

A process for producing elastomeric composition is provided comprising mixing at least one elastomer, at least one cellulose ester additive, at least one methylene acceptor, at least one methylene donor, and optionally, at least one filler; wherein the cellulose ester additive comprises at least one cellulose ester. The cellulose ester additive can also comprise at least one compatibilizer and/or plasticizer.
