Abstract: This invention relates to a blend comprising (a) about 2% to about 98% by weight of at least one ester of cellulose comprising an alkanoyl chain having from about 1 to about 10 carbon atoms, and having at a D.S. of about 2.3 to about 3.0, and an inherent viscosity of about 0.2 to about 3.0 deciliters/gram as measured at a temperature of 25° C. for a 0.5 g sample in 100 ml of a 60/40 parts by weight solution of phenol/tetrachloroethane, and (b) about 98% to about 2% by weight of at least one ester of cellulose comprising an alkanoyl chain having from about 1 to about 10 carbon atoms, and having a D.S. of about 1.5 to about 2.2, and an inherent viscosity of about 0.2 to about 3.0 deciliters/gram as measured at a temperature of 25° C. for a 0.5 g sample in 100 ml of a 60/40 parts by weight solution of phenol/tetrachloroethane, said percentages being based on the weight of component (a) plus component (b).

Abstract: 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.

Abstract: This invention provides cellulose ester fibers having an intermediate degree of substitution per anhydroglucose unit (DS/AGU) along with pigments which act as photooxidation catalyst. The fibers are useful as filler materials for tobacco products. The filter materials thus provided are easily dispersible and biodegradable and do not persist in the environment.
