Patent number: 8871140Abstract: Disclosed herein is a method of manufacturing inorganic hollow yarns, such as cermets, oxide-non oxide composites, poorly sinterable non-oxides, and the like, at low costs. The method includes preparing a composition comprising a self-propagating high temperature reactant, a polymer and a dispersant, wet-spinning the composition through a spinneret to form wet-spun yarns, washing and drying the wet-spun yarns to form polymer-self propagating high temperature reactant hollow yarns, and heat-treating the polymer-self propagating high temperature reactant hollow yarns to remove a polymeric component from the polymer-self propagating high temperature reactant hollow yarns while inducing self-propagating high temperature reaction of the self-propagating high temperature reactant to form inorganic hollow yarns. The composition comprises 45˜60 wt % of the self-propagating high temperature reactant, 6˜17 wt % of the polymer, 0.1˜4 wt % of the dispersant, and the balance of an organic solvent.Type: GrantFiled: June 18, 2013Date of Patent: October 28, 2014Assignee: Korea Institute of Energy ResearchInventors: Churl-Hee Cho, Do-Kyung Kim, Jeong-Gu Yeo, Young-Soo Ahn, Dong-Kook Kim, Hong-Soo Kim

Publication number: 20140272368Abstract: Cellulose diester films that include a cellulose diester; a plasticizer; a colorant; and an opacity additive may be useful for playing cards. In some instances, forming cellulose diester films may include preparing a dope that comprises a cellulose diester, a plasticizer, and a solvent; introducing a colorant and an opacity additive into the dope to yield a casting dope; and casting the casting dope into a cellulose diester film. Playing cards may then be produced by methods including, for example, cutting the cellulose diester film and printing on the cellulose diester film.Type: ApplicationFiled: March 12, 2014Publication date: September 18, 2014Applicant: Celanese Acetate LLCInventor: Steve Herod

Publication number: 20030097963Abstract: Polymer film, coating, and molded article elements for use in a display device are described which comprise a polymer phase having molecularly dispersed therein an acid scavenger compound, a hindered amine light stabilizer compound and a hindered phenol antioxidant compound, wherein the hindered amine light stabilizer compound and the hindered phenol antioxidant compound are present at a weight ratio of from 20:1 to 1:20, and the weight ratio of the acid scavenger compound to the total concentration of hindered amine light stabilizer compound and hindered phenol antioxidant compound is from 10:1 to 1:10. Use of a combination of an acid scavenger and a combination of two radical scavenger antioxidants dispersed in a polymer phase in accordance with the invention enables enhanced stabilization of the polymer when exposed to high heat and/or humidity condition, which has been found to be especially desirable when applied to polymer layers laminated into displays (e.g., polarizers in liquid crystal displays).Type: ApplicationFiled: May 17, 2002Publication date: May 29, 2003Applicant: Eastman Kodak CompanyInventors: Timothy C. Schunk, Kurt M. Schroeder, Charles H. Appell, Daniel T. Linehan
