Patent number: 7244779Abstract: A resin composition provides good optical properties when stretched and efficient oxygen-scavenging, the resin composition comprising a film-forming polyester and an effective amount of oxygen-scavenging particles, wherein the particles have a particle size distribution such that particles of less than about 25 microns in size do not exceed a concentration defined by a formula that includes the apparent density of the particles. Another resin composition comprises a film-forming polyester and from about 50 to about 2500 parts by weight of iron per million by weight of the resin, wherein the amount of iron particles having a size of less than about 20 microns does not exceed about 800 parts per million by weight of the resin. A method is also provided for incorporating high levels of oxygen-scavenging particles into a film-forming polyester resin composition with low haze when stretched.Type: GrantFiled: March 24, 2004Date of Patent: July 17, 2007Assignee: M & G USA CorporationInventors: Deborah Tung, Edwin A. Sisson, Roy A. Leckonby

Patent number: 7199171Abstract: The present invention provides a (meth)acrylic resin composition, in which thermal degradation when processing is inhibited and discoloring hardly occurs, which could not be obtained in the conventional (meth)acrylic resin composition containing (meth)acrylic resin prepared by suspension polymerization. More specifically, the present invention relates to a (meth)acrylic resin composition comprising 100 parts by weight of a methyl methacrylate polymer obtained by suspension polymerizing 50 to 100% by weight of methyl methacrylate and 50 to 0% by weight of a monomer copolymerizable therewith, 1 to 200 parts by weight of a copolymer having a multi-layer structure and 0.02 to 10 parts by weight of a fatty acid metallic salt.Type: GrantFiled: January 5, 2004Date of Patent: April 3, 2007Assignee: Kaneka CorporationInventor: Hideyuki Sakamoto

Patent number: 7186766Abstract: About 0.001 to 1 part by weight of a phenol component (B1) and/or about 0.001 to 10 parts by weight of an amino acid (B2) are added relative to 100 parts by weight of a polyacetal resin (A) to prepare a polyacetal resin composition. The phenol component (B1) may be a novolak phenol-series resin, a phenol aralkyl-series resin, a polyvinyl phenol-series resin, a polyhydric phenol, a polyphenol, a catechin compound, or a lignin. The amino acid (B2) may be an ?-amino acid, a ?-amino acid, a ?-amino acid, a ?-amino acid, or a derivative of an amino acid. The polyacetal resin composition may further contain an antioxidant, a heat stabilizer, a processing stabilizer, a weather (light)-resistant stabilizer, or a coloring agent. The polyacetal resin composition ensures marked inhibition of formaldehyde emission.Type: GrantFiled: July 1, 2003Date of Patent: March 6, 2007Assignee: Polyplastics Co., Ltd.Inventors: Hatsuhiko Harashina, Hayato Kurita

Patent number: 7179849Abstract: The present invention relates to antimicrobial compositions, methods for the production of these compositions, and use of these compositions with medical devices, such as catheters, and implants. The compositions of the present invention advantageously provide varying release kinetics for the active ions in the compositions due to the different water solubilities of the ions, allowing antimicrobial release profiles to be tailored for a given application and providing for sustained antimicrobial activity over time. More particularly, the invention relates to polymer compositions containing colloids comprised of salts of one or more oligodynamic metal, such as silver. The process of the invention includes mixing a solution of one or more oligodynamic metal salts with a polymer solution or dispersion and precipitating a colloid of the salts by addition of other salts to the solution which react with some or all of the first metal salts.Type: GrantFiled: August 26, 2003Date of Patent: February 20, 2007Assignee: C. R. Bard, Inc.Inventor: Richard N. Terry
