Patent
Eastman Chemical Company | Date: 2016-11-04

The invention is generally directed to sports bottles and other articles produced by blow molding from polymeric materials containing isosorbide having glass transition temperatures ranging from 90 C. to 130 C., as well as to processes for producing them. These articles can be exposed to water at high tempeatures and can be produced by using a suitable combination of a stretch ratio of less than 3 and a preform temperature at least 20 C. greater than the glass transition temperature (Tg) of the polymeric material.

Degradable materials are provided that may be utilized in various wellbore treatment fluids, such as hydraulic fracturing fluids. In particular, the degradable materials can be formed from cellulose esters that are capable of effectively degrading at specific rates when exposed to the aqueous environments commonly found in wellbores. More particularly, the degradable materials can be in the form of degradable fibers that are formed from the cellulose esters described herein.

Objects can be produced using an additive manufacturing process and the objects can be removed from the substrates on which the objects are formed. An object can include a plurality of layers of a polymeric material that includes units of a diacid component and units of a glycol component. A process can be used to form the object that includes depositing a plurality of layers of the polymeric material onto a substrate to form the object. In some cases, the plurality of layers are deposited onto the substrate according to a predetermined design.

A reaction system for forming a thermoset urethane or polyurethane comprising at least one polyol, at least one isocyanate, and a zinc-containing catalyst. In some aspects, the polyol may be a monomeric polyol comprising secondary hydroxyl groups or it may be a polymeric polyol comprising residues of the monomeric polyol. The zinc-containing catalyst may be effective for catalyzing the reaction of the polyol and isocyanate, particularly when at least a portion of the secondary hydroxyl groups in the monomeric or polymeric polyol are hindered secondary hydroxyl groups. Urethanes and polyurethanes formed as described herein may be used in coating compositions, including powder coating compositions, solvent-based coating compositions, and waterborne coating compositions, as well as in many other applications.

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).
