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 coating composition containing (A) a sulfopolyester, (B) water, and (C) a polymer resin. The sulfopolyester comprises residues of (a) an acid component comprising (i) a dicarboxylic acid compound, a derivative of a dicarboxylic acid compound, or combinations thereof and (ii) a sulfomonomer having at least one ionic sulfonate group covalently bonded directly or indirectly to an aromatic or cycloaliphatic ring and (b) a polyhydroxyl component comprising a 2,2,4,4-tetralkylcyclobutane-1,3-diol. The polyhydroxyl component may further contain residues of 1,4-cyclohexanedimethanol, neopentyl glycol, or a mixture thereof.

A commercial scale system and process for chemically modifying wood and then heating the chemically-modified wood. The system/process separates the chemical modification step from the heating step by utilizing two different vessels for the modification and heating steps. The system and process can, in certain situations, include a containment room for preventing escape of vapors from a chemical wood modification reactor, a wood heater, and/or a chemically-modified bundle of wood as the bundle is transported from the wood modification reactor to the wood heater.

Disclosed are fibers comprising one or more branded fibers which exhibit surface markings in a repeated pattern along the length of the branded fibers. The branded fibers can be incorporated into yarns or fiber bands to represent supply chain information of the yarns, fiber bands, and/or articles made from the yards or fiber bands. In a specific example, branded fibers can be incorporated into an acetate tow band The branded fibers can be recovered from a cigarette filter, the repeated pattern decoded, and supply chain information associated with the acetate tow used to make the cigarette filter, such as manufacturer, customer, ship to location, and even the acetate tow bale, can be obtained.

Disclosed are a variety of amphoteric compounds having a heterocyclic quaternary nitrogen group. The heterocycle includes pyridines, piperidines, and pyrrolidines, and is linked to the hydrophobe via either an amide or an ester linkage. These hetereocyclic amphoteric compounds can be advantageously prepared in high yield and purity by a two-step chemoenzymatic process, and have excellent surfactant properties.

Disclosed is a process for the reductive carbonylation of a low molecular weight alcohol to produce the homologous aldehyde and/or alcohol. The process includes conducting the reaction to produce the aldehyde in the presence of a single component catalyst complex composed of cobalt, an onium cation and iodide in a ratio of 1:2:4 without additional promoters. A ruthenium co-catalyst is used in the production of the homologous alcohol. The reductive carbonylation reaction does not require an additional iodide promoter and produces a crude reductive carbonylation product substantially free of methyl iodide.
