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

The present disclosure relates to polymer coating compositions that comprise at least one thermoplastic resin, at least one opacity modifier, at least one gloss modifier, and at least one impact modifier, articles at least partially coated with the polymer coating composition, paintable polymer coated articles and method for making the polymer coated and painted polymer coated articles. These compositions exhibit enhanced paintability (including paintability with water-based paints) and mechanical properties for fabrication (cutting, nailing, routing, etc.), while maintaining acceptable visual appearance, such as, for example, opacity, gloss, surface appearance, and surface roughness.

Thermoplastic formulations for enhanced paintability, toughness and melt processability

Polyesters and polyester containers having a reduced coefficient of friction and improved clarity are produced using an antiblock agent comprising a dried talc having from about 20 to about 300 ppm water or a fatty acid tethered talc. The use of these talcs result in polyesters and polyester containers having a coefficient of less than about 1.0 and a clarity with haze values of less than about 4%.

Polyesters and polyester containers having a reduced coefficient of friction and improved clarity

A solid concentrate is provided having a combination of a transition metal present in an amount ranging from 1000 to 40,000 ppm (weight by metal) and a polyester polymer present in an amount of at least 40 wt. % based on the weight of the concentrate. Concentrates made with highly modified polyester polymers are easy to compound with transition metals forming less brittle polymer upon melt extrusion. Bottle preforms and oxygen scavenging bottles can be made from these concentrates by combining solid polyester particles, solid polyamide particles, and solid these concentrate particles c into an melt processing zone, forming a melt, and forming an article directly from the melt. The b* color and the L* color and the haze levels of the preforms are improved over the preforms made with liquid carriers instead of solid concentrates. The particles are also advantageously simultaneously dried in a drying zone under conditions effective to at least partially remove moisture from the blend to thereby further improve the b* color and L* color.

Polyester based cobalt concentrates for oxygen scavenging compositions

Disclosed are novel compositions for the preparation of void-containing articles comprising a polymer matrix and a voiding agent The voiding agent comprises at least one first polymer and at least one second polymer, which are selected on the basis of physical properties such as glass transition temperature, tensile modulus, melting point, surface tension, and melt viscosity. Shaped articles such as sheet, film, bottles, tubes, labels, and sleeves may prepared from these compositions. Also disclosed are polyester shrink films prepared using a voiding agent comprising a novel blend of cellulosic and olefinic polymers. The resulting shrink films have better opacity, lower density, reduced shrink force, and improved printability as compared with most standard voiding agents. The films are useful for sleeve label and other shrink film applications and their lower density allows them to be readily separated from soft drink bottles, food containers and the like during recycling operations.

Compositions for the preparation of void-containing articles

An ultraviolet absorption composition has been developed for the protection of packaging or container contents in the ultraviolet range of 290 nm to 390 nm, offering effective screening from all wavelengths of solar radiation. A combination of an optical brightener with an ultraviolet absorber has been found to provide effective screening without adding significant color to the polymer composition. This extended range of ultraviolet blocking over what can be achieved with ultraviolet absorbers alone is especially valuable in food and drink packaging applications where the contents of the packages need ultraviolet protection to prevent discoloration or development of undesirable flavors.

The use of these talcs results in polyesters and polyester containers having a coefficient of less than about 1.0 and a clarity with haze values of less than about 4%.

This invention is directed to a polymer-clay nanocomposite, products produced from the nanocomposite, and a process for preparing a polymer-clay nanocomposite. The polymer-clay nanocomposite comprises (a) a matrix polymer, (b) an amorphous oligomer, and (c) a layered clay material.
