20160040007 | COMPOSITION FOR MAINTAINING GOOD COLOR WHEN THERMALLY TREATING POLYESTER-POLYAMIDE BLENDS - A polymer composition and wall of a container made from such composition is set forth comprising a polyamide and polyester and a sufficient amount of an interfacial tension reducing agent such that the polyamide domains stretch disproportionately to the amount of stretch experienced by the polyester both with and without a cobalt salt. | 02-11-2016 |
20140308532 | COMPOSITION FOR MAINTAINING GOOD COLOR WHEN THERMALLY TREATING POLYESTER-POLYAMIDE BLENDS - A specially structured article is described which allows products made from the article to undergo a second heating without a dramatic color shift. This permits more recycled products from the material used to make the article. | 10-16-2014 |
20140220281 | OXYGEN SCAVENGERS - Described herein are oxygen scavengers, oxygen scavenging polymeric compositions, and oxygen scavenging articles. The polymeric compositions comprising the oxygen scavengers may have utility in packaging, sealing, wrapping, and storing oxygen-sensitive substances, e.g., to preserve freshness of foods, beverages, and the like. | 08-07-2014 |
20140107300 | DISPERSIONS OF HIGH CARBOXYL POLYAMIDES INTO POLYESTERS - A polymer composition, stretched and unstretched articles and processes to make stretched and unstretched articles from that composition are set forth wherein the composition comprises a blend of a polyamide wherein the amino to carboxyl end group ratio of the polyamide polymer is less than 1.0 when the relative viscosity of the polyamide polymer is less than 2.0, and less than 0.30 when the relative viscosity is in the range of 2.0 to 2.3 and less than 0.20 when the relative viscosity is greater than 2.3, a crystallizable polyester and an interfacial tension reducing agent. | 04-17-2014 |
20130260071 | POLYAMIDE-POLYDIENE BLENDS WITH IMPROVED OXYGEN REACTIVITY - This application discloses the use of polyamide-polydiene blends to improve the oxygen reactivity in the presence of ionic polyester compatibilizers. | 10-03-2013 |
20130072603 | COLOR CONTROL OF POLYESTER-COBALT COMPOUNDS AND POLYESTER-COBALT COMPOSITIONS - The present invention is to a composition made from a polyester produced by the acid or ester polyester process, a cobalt salt and a base, preferably an alkaline metal base. The composition can be made by blending a cobalt salt with a polyester which has been polymerized in the presence a alkaline metal ion derived from a basic alkaline metal compound, e.g. alkaline metal base or basic alkaline metal salt. The composition may optionally comprise an ionic compatibilizer, which may further be blended with a partially aromatic polyamide. This blend can be processed into a container having both active and passive oxygen barrier with an improved color and clarity than that achieved by cobalt alone. The use of the cobalt salt in combination with the base can also be used to improve the color of recycled polyester durin processing. | 03-21-2013 |
