Patent number: 10323131Abstract: The invention is a composition that can prevent formation in, or scavenge undesirable organic materials from, a polymer matrix. The composition contains cyclodextrin and particles of activated carbon. The composition can scavenge thermal decomposition products that can be produced during melt processing of a polymer, contaminants inherent in a polymer, or other types of impurities from a polymer matrix that otherwise may elute into the air, a water supply, or an ingestible material such as a food, a drug, or a beverage. Other aspects of the invention are blends of the composition with polymeric materials, methods of making blends, articles containing the composition, and methods of making articles containing the composition.Type: GrantFiled: April 27, 2016Date of Patent: June 18, 2019Assignee: Cellresin Technologies, LLCInventor: Willard E.

Patent number: 10212931Abstract: Cyclodextrin compositions, including a hydrophobic carrier and a cyclodextrin complex, are formed and disposed on a variety of substrates using conditions that avoid substantial loss of the complexed compound from the cyclodextrin complex, even where the complexed compound is a gas a common ambient temperatures (e.g. 20° C.). Flexographic printing is particularly useful for disposing the cyclodextrin compositions on one or more substrates. Substrates treated with the cyclodextrin complexes are useful for subsequent release of the complexed compound.Type: GrantFiled: June 19, 2017Date of Patent: February 26, 2019Assignees: Kimberly-Clark Worldwide, Inc., Cellresin Technologies, LLCInventors: Willard E.

Patent number: 10035128Abstract: Compositions that can be used to adsorb low concentration, of unwanted or target substances from a dynamic fluid stream or from an enclosed static vapor phase. Such adsorbency can be obtained with thermoplastic materials used in the form of bulk polymer or a film, fiber, web, woven fabric, non-woven fabric, sheet, packaging and other such structures including or surrounding the enclosed volume. The concentration should be reduced to non-offensive sensed limits or a limit that does not produce a biological response.Type: GrantFiled: October 17, 2017Date of Patent: July 31, 2018Assignee: Cellresin Technologies, LLCInventor: Willard E.

Patent number: 9642356Abstract: Thermoplastic polyolefin polymer compositions, polymer chips, fibers, woven or nonwoven fabrics, films, closures, and laminates include a polymer and cyclodextrin compound with a volatile maturation inhibitor or an olefinic ethylene receptor antagonist in respiring produce materials. The polymer composition can also include a cyclodextrin-modified polymer or a substituted cyclodextrin. Olefinic ethylene inhibitors can be formed in the cyclodextrin composition, wherein the cyclodextrin releases the olefinic inhibitor composition when used in produce packaging materials. Coating compositions can also be made. The inhibitor is introduced into the materials and is released under controlled conditions of humidity. Upon release, the olefinic inhibitor blocks ethylene receptor sites on proteins that control maturation and can produce an extended period during which the produce does not substantially complete maturation or ripening to a degree leading to spoilage.Type: GrantFiled: December 14, 2010Date of Patent: May 9, 2017Assignee: Cellresin Technologies, LLCInventors: Willard E. Wood, Neil J. Beaverson, William J. Kuduk
