Abstract: Provided are certain cellulose ester compositions which serve as improved anti-tack additives for various thermoplastic polymers, in applications such as woven and non-woven fibers, laminates including the composition, fabrics including the composition, apparel and garments, textiles including the composition, etc.

Abstract: Degradable particulate materials are provided that may be utilized in various wellbore treatment fluids, such as hydraulic fracturing fluids. In particular, the degradable particulate materials can be formed from a cellulosic polymer, a polyester polymer, a polyvinyl alcohol, or a guar gum ester that are capable of effectively degrading at specific rates when exposed to the aqueous environments in low temperature wellbores (50° C. to 100° C.).

Abstract: This patent application discloses membranes comprised of cellulose esters that are crosslinked. The membrane can be in the form of a flat film, tube or hollow fiber membrane. The membranes are plasticization resistant and can be used to separate gases.

Abstract: A method of making a facile, surface-independent, polyphenol coating is disclosed. In general, the method includes contacting at least a portion of the substrate to be coated with an aqueous solution containing one or more salts and one or more nitrogen-free phenolic compounds. Substrates of all kinds may be used, and compounds used to make the coating may include epigallocatechin-3-gallate (EGCG), epigallocatechin (EGC) and epicatechin-3-gallate (ECG), tannic acid, gallic acid, pyrogallol, and/or other nitrogen-free phenolic compounds. The coating made using the method, methods of using the coating, and kits comprising the coating precursors are also disclosed.

Abstract: The present invention provides adhesive hydrogels that negatively swell at physiological temperature. By combining mussel-mimetic chemistry and the thermosensitive nature of poly(ethylene oxide)-poly(propylene oxide) copolymers, novel materials were designed that are suitable as medical sealants and adhesives.

Abstract: The present invention encompasses biocompatible reactants, biocompatible product hydrogels, methods of use thereof, and methods of synthesis thereof using a novel crosslinking mechanism between a first reactant compound including an N-Hydroxysuccinimide (NHS) ester group and a second reactant compound including a N-terminal cysteine amine group. In certain embodiments, one or more of the reactant compounds may be a macromonomer.
