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 %.

Self-corrugating laminates useful in the manufacture of thermoelectric devices are disclosed. The laminates include an upper and a lower shrinkable film layer and a non-shrinkable core with a thermoelectric pattern formed thereon bonded between said upper and lower shrinkable film along bond lines arranged parallel, substantially parallel, radially, or annularly. The bond lines that bond the upper shrinkable film layer to top surface of the nonshrinkable core are staggered relative to the bond lines that bond the lower shrinkable film layer to the bottom surface of the non-shrinkable core such that upon shrinkage of the shrinkable film layers, structural corrugations are formed in the non-shrinkable core. Thermoelectric modules or devices and methods for forming them from the self-corrugating laminates are also described.

Polymer composite materials comprising of least one polymer resin and platelet particles from at least one layered silicate material uniformly dispersed in the resin and articles prepared from the polymer composite materials. The polymer composite contains at least one polyamide resin, at least one oxygen scavenging system, and at least one layered silicate material. These polymer composite materials are especially useful for manufacturing clear polyester bottles and polyester film that are recyclable have improved active gas barrier properties to oxygen, and have improved passive barrier properties to carbon dioxide and other gases. The polymer composite materials can be used in relatively minor amounts as either a blend or a coextruded thin layer with virgin or post consumer recycled polyesters and related copolymners.

This invention describes the use of organoclays as additives to plasticizers to provide a plasticizer composition, to allow the mixing of the plasticizers with thermoplastic resins in the same process used to convert the resin formulation to finished product. The use of this invention eliminates the need for a preliminary compounding step to incorporate plasticizers into thermoplastics prior to extrusion or molding.

A thermoplastic molding composition having a high neat deflection temperature but a relatively low melt extrusion temperature is formed by blending a polyetherimide with about 35 to about 80 weight percent of a copolyester of terephthalic and/or isophthalic acid and a glycol component comprising ethylene glycol and up to about 60 mol percent of 1,4-cyclohexanedimethanol. The blend also has a high flexural modulus and can be used to form plastic articles that can be molded at moderate temperatures but retain flexural strength at elevated temperatures. Certain compositions of the invention are clear, single phase solid solutions.
