A tire is provided comprising a cellulose ester/elastomer composition wherein the cellulose ester/elastomer comprises at least one cellulose ester, at least one elastomer, and at least one additive selected from the group consisting of at least one compatibilizer and at least one plasticizer.

Tires comprising cellulose ester/elastomer compositions

This invention provides cellulose ester interpolymers, and methods of oxidizing cellulose interpolymers and cellulose ester interpolymers. The invention also provides routes to access carboxylated cellulose ester derivatives with high acid numbers wherein the carboxyl group is attached directly to the cellulose backbone by a carbon-carbon bond. Through functionalization of an intermediate aldehyde, the corresponding cationic or zwitterionic cellulose ester derivatives can also be accessed. The interpolymers of the present invention have a number of end-use applications, for example, as binder resins in various types of coating compositions and as drug delivery agents.

Cellulose interpolymers and method of oxidation

A cellulose ester composition is provided comprising at least one cellulose ester and at least one additive selected from the group consisting of a compatibilizer, and a plasticizer. Processes for producing the cellulose ester composition are also provided. In another embodiment, a cellulose ester/elastomer composition is provided comprising at least one elastomer, at least one cellulose ester; and at least one additive; wherein the additive is at least one selected from the group consisting of a compatibilizer and a plasticizer. Processes for producing the cellulose ester/elastomer composition is also provided as well as articles comprising the cellulose ester/elastomer composition.

The invention provides a method of separating from corn fiber a lipid fraction having phytosterol esters and phytosterols where the method has the steps of: (a) heating an aqueous mixture of unground corn fiber; (b) contacting the mixture of step (a) with at least one enzyme suitable for digesting starch for a time and at a temperature suitable to provide a mixture of an essentially destarched corn fiber and a liquid comprising soluble carbohydrates; (c) contacting the mixture of step (a) or (b) with a protease enzyme to provide a proteolyzed corn fiber and a liquid; (d) separating the liquid of step (c) from the corn fiber to provide a destarched, proteolyzed corn fiber; and (e) extracting the destarched, proteolyzed corn fiber with at least one organic solvent. A corn fiber lipid fraction/organic solvent solution having phytosterol esters and phytosterols is provided. The invention also provides a corn fiber lipid fraction containing phytosterols and phytosterol esters obtained via solvent extraction of a proteolyzed corn fiber. The concentration of phytosterols and phytosterol esters in the lipid fraction is at least about 1.4 times greater than the concentration of phytosterols and phytosterol esters in the lipid fraction of a nonproteolyzed corn fiber.

Methods of separating a corn fiber lipid fraction from corn fiber

The invention provides a method of obtaining a cellulose material from corn fiber wherein the method comprises the steps of: (a) heating a mixture of corn fiber and a liquid; (b) contacting the mixture of step (a) with a protease enzyme, thereby providing a proteolyzed corn fiber and a liquid; (c) separating the liquid from the proteolyzed corn fiber; (d) contacting the proteolyzed corn fiber at least once with an alkaline extractant, thereby providing an insoluble cellulose material and a first liquid comprising arabinoxylan; (e) separating the insoluble cellulose material from the first liquid comprising arabinoxylan at a temperature of at or above about 60&deg; C.; and (f) rinsing the insoluble cellulose material to remove essentially all alkali, thereby providing a cellulose material having a cellulose content of at least about 50% and consisting essentially of cellulose I. Cellulose esters and ethers are also prepared from the derivatizable cellulose prepared according to the methods herein.

This invention relates to a new composition of matter which comprises hydroxybutenyl derivatives of cyclodextrins (HBenCD) or mixed ethers of cyclodextrins where at least one of the ether substituents is hydroxybutenyl (HBenRCD where R is an ether substituent other than hydroxybutenyl). This invention also relates to novel processes for the preparation of cyclodextrin ethers. This invention further relates to inclusion complexes formed between HBenCD or HBenRCD and guest molecules. Such inclusion complexes are useful in pharmaceutical, cosmetic, and food applications. Furthermore, this invention relates to the incorporation of HBenCD or HBenRCD or their inclusion complexes in thermoplastic materials, textiles or membranes.

Cyclodextrin ethers

In one aspect, the invention provides a method of extracting arabinoxylan from corn fiber wherein the method comprises the steps of: (a) heating an aqueous mixture of corn fiber and a liquid; (b) contacting the mixture of step (a) with a protease enzyme, thereby providing a proteolyzed corn fiber and a liquid; (c) separating the liquid from the proteolyzed corn fiber; (d) contacting the proteolyzed corn fiber at least once with an alkaline extractant, thereby providing an insoluble cellulose material and a liquid comprising arabinoxylan; (e) separating the insoluble cellulose material from the liquid comprising arabinoxylan; and (f) reducing the volume of the liquid comprising arabinoxylan by removing excess alkaline extractant, thereby providing a concentrated liquid comprising from about 10% to about 50% solids, wherein the solids comprise arabinoxylan. In a further aspect, the invention provides methods of preparing novel arabinoxylan esters and ethers. Still further, the invention provides novel arabinoxylan esters and ethers.
