Patent number: 8309622Abstract: Oxygen-scavenging polymers and packaging for holding oxygen-sensitive products. A heat treatment process has been found to significantly increase the oxygen-scavenging performance of the polymer. The enhanced scavenging polymer can be effectively incorporated into various packaging, including transparent multilayer containers for beer and juice.

Patent number: 7959836Abstract: Disclosed is a process for the preparation of shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles, having high transparency and low haze, and comprising immiscible blends of at least one polyester comprising 2,2,4,4-tetramethyl-1,3-cyclobutanediol, and a copolyamide or a transamidized, homogeneous blend of a least two polyamides. The components of the immiscible blend have refractive indices which differ by about 0.006 to about ?0.0006. The small difference in the refractive indices enable the incorporation of regrind into the polymer composition to produce transparent shaped articles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into the compositions to produce shaped articles having oxygen-scavenging properties.Type: GrantFiled: March 28, 2006Date of Patent: June 14, 2011Assignee: Eastman Chemical CompanyInventors: Wesley Raymond Hale, Thomas Joseph Pecorini, Mark Edward Stewart, Martin Emerson Rogers, Spencer Allen Gilliam, Michael Duane Cliffton, Emmett Dudley Crawford, David Scott Porter, Gary Wayne Connell, Marcus David Shelby

Patent number: 7947773Abstract: An electrically conductive composite material includes metallic nanostrands distributed throughout a matrix constructed of a polymer, ceramic, or elastomer. The nanostrands may have an average diameter under four microns and an average aspect ratio over ten-to-one. Larger fibers may also be included to enhance electrical conductivity or other properties. The nanostrands and/or fibers may be magnetically oriented to enhance electrical conductivity along one direction. A pressure sensor may be formed by utilizing an elastomer for the matrix. Electrical conductivity through the composite material varies in proportion to deflection of the elastomer. A composite material may be applied to a surface as an electrically conductive paint. Composite materials may be made by cutting a blank of the nanostrands to the desired shape, inserting the matrix, and curing the matrix. Alternatively, a suspension agent may first be used to dispose powdered nanostrands in the desired shape.Type: GrantFiled: December 11, 2006Date of Patent: May 24, 2011Assignee: Conductive Composites Company, L.L.C.Inventors: George Clayton Hansen, Lauren Hansen, William C.

Patent number: 7943216Abstract: The present invention comprises a blend of polyester and a partially aromatic polyamide with an ionic compatibilizer and a cobalt salt. This blend can be processed into a container that has both active and passive oxygen barrier and carbon dioxide barrier properties at an improved color and clarity than containers known in the art. The partially aromatic polyamide is preferably meta-xylylene adipamide. The ionic compatibilizer is preferably 5-sodiumsulfoisophthalic acid or 5-zincsulfoisophthalic acid, or their dialkyl esters such as the dimethyl ester (SIM) and glycol ester (SIPEG). The cobalt salt is selected form the class of cobalt acetate, cobalt carbonate, cobalt chloride, cobalt hydroxide, cobalt naphthenate, cobalt oleate, cobalt linoleate, cobalt octoate, cobalt stearate, cobalt nitrate, cobalt phosphate, cobalt sulfate, cobalt (ethylene glycolate), or mixtures of two or more of these.
