Patent
Eastman Chemical Company | Date: 2017-05-03

Disclosed are fibers which contain identification fibers. The identification fibers can contain a one or more of chemical markers and one or more distinct features, or taggants, which may vary among the fibers or be incorporated throughout all of the fibers. The chemical markers and distinct features can be representative of specific supply chain information. The supply chain information can be used to track the fibers from manufacturing through intermediaries, conversion to final product, and/or the consumer. The disclosed embodiments also relate to the method for making and characterizing the fibers. Characterization of the fibers can include identifying chemical markers and distinct features and correlating the chemical markers and distinct features to manufacturer-specific taggants to determine supply chain information.

Objects can be produced using an additive manufacturing process. The objects can include a plurality of layers of a polymeric material that includes a copolyester ether. The copolyester ether can include units of a diacid component and units of a glycol component. In some implementations, the units of the diacid component can be derived from at least one aliphatic dicarboxylic acid. Further, in some illustrative examples, the units of the glycol component can be derived from an aliphatic glycol and a polyalkylene ether glycol. In some cases, the polymeric material can also include a thermoplastic elastomer and a resin component.

The invention is directed to a process for preparing a 1,4-disubstituted cyclohexane compound of Formula (I): where A is -OH, -OR, Br, or CI; and R is a silyl group, a hydrocarbyl group, or an acyl group having 1 to 12 carbon atoms. The process includes the steps of reacting ethylene with a (2E,4E)-hexa-2,4-diene compound to produce a 3,6-disubstituted cyclohex-1 - ene compound, and hydrogenating the 3,6-disubstituted cyclohex-1 -ene compound to yield the 1,4-disubstituted cyclohexane compound of formula (I).

Disclosed is an oxidation process to produce a crude carboxylic acid product carboxylic acid product. The process comprises oxidizing a feed stream comprising at least one oxidizable compound to generate a crude carboxylic acid slurry comprising furan-2,5-dicarboxylic acid (FDCA) and compositions thereof. Also disclosed is a process to produce a dry purified carboxylic acid product by utilizing various purification methods on the crude carboxylic acid.

Amorphous propylene-ethylene copolymers are described herein that can include high amounts of ethylene and exhibit desirable softening points and needle penetrations. The desirable combinations of softening points and needle penetrations in these propylene-ethylene copolymers allow them to have a broad operating window. Due their broad operating window, the propylene-ethylene copolymers can be utilized in a wide array of applications and products, including hot melt adhesives.


Described are polyesters comprising (a) a dicarboxylic acid component comprising 80 to 100 mole % terephthalic acid residues; optionally, 0 to 20 mole % aromatic dicarboxylic acid residues or aliphatic dicarboxylic acid residues; 20 to 30 mole % of 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and 70 to 80 mole % 1,4-cyclohexanedimethanol residues. The polyesters may be manufactured into articles such as fibers, films, bottles or sheets.

The present invention relates to films made from cellulose tricacetate having low hydroxyl content and certain plasticizers. These films can exhibit low or zero optical retardation values, making them particularly suitable for use in optical applications, such as in liquid crystal displays (LCD) as protective and compensator films.

An object can be formed in an additive manufacturing process, such as FDM, by providing a substrate having at least a surface that is made of a first material, and forming one or more layers of a second material on the surface of the substrate, wherein a Hildebrand solubility parameter of the second material is within about 5% of a Hildebrand solubility parameter of the first material. In this manner, the object part formed by the one or more layers of the second material may be incorporated into the object. In an example, the object includes a first portion comprised of the one or more layers of the second material and a second portion comprised of the substrate, the first portion having a first haze value and the second portion having a second haze value, wherein a percent difference between the first haze value and the second haze value is equal to or greater than about 165%.


This invention relates to novel compositions comprising regioselectively substituted cellulose esters. One aspect of the invention relates to processes for preparing regioselectively substituted cellulose esters from cellulose dissolved in ionic liquids. Another aspect of the invention relates to the utility of regioselectively substituted cellulose esters in applications such as protective and compensation films for liquid crystalline displays.
