Patent number: 11732165Abstract: This invention pertains to a curable composition comprising a first component having ?-ketoester and/or malonate functionalities and a second component having two or more aldehyde functionalities. The compositions can be cured at room temperature or low temperatures to yield crosslinked networks that are capable of providing desirable properties for coating and adhesive applications. The reactive functionalities of ?-ketoester, malonate, and aldehyde can be either on polymers as the main binders or on small molecules as the crosslinkers. The curable compositions desirably are either solventless or organic solvent based.Type: GrantFiled: December 6, 2019Date of Patent: August 22, 2023Assignee: Eastman Chemical CompanyInventors: Thauming Kuo, Vasudev R.

Patent number: 10941337Abstract: Suspension of proppants in hydraulic fracturing applications can be strongly affected by the cross-sectional shapes and lengths of the fibers present in the wellbore treatment compositions. For instance, it has been observed that crimped cellulose ester fibers with a trilobal cross-section and an optimized length can provide enhanced suspension of proppants in aqueous fracturing fluids. Furthermore, the present invention demonstrates that non-round cellulose ester fibers can provide superior proppant suspension properties relative to polylactic acid fibers with a round cross-section.Type: GrantFiled: October 11, 2017Date of Patent: March 9, 2021Assignee: Eastman Chemical CompanyInventors: Nick Allen Collins, S M Bedarul Islam, Phillip Michael Cook, Koushik Ghosh

Patent number: 10465490Abstract: A fiber delivery system capable of providing cut fiber segments for use in treating an oil and/or gas well. The fiber delivery system can utilize bales of a continuous filamentary tow that are transported to the well site from a remote manufacturing location. At the well site, a multifilament strand can be pulled off the bale, opened, and cut to provide cut fiber segments. The cut fiber segments can be mixed with other well treatment components to create a well treatment medium that is introduced into the well as part of a drilling, stimulation, or cementing process.Type: GrantFiled: July 18, 2016Date of Patent: November 5, 2019Assignee: Eastman Chemical CompanyInventors: Nick Allen Collins, S.
