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. The partially aromatic polyamide is present in a range from about 1 to about 10 wt. % of said composition.Type: GrantFiled: April 27, 2010Date of Patent: May 17, 2011Assignee: INVISTA North Americal S.ar.l.Inventors: Zhenguo Liu, Sanja Mehta, Xiaoyan Huang, David A Schiraldi

Publication number: 20110098393Abstract: A highly heat-resistant fluororesin, such as tetrafluoroethylene resin or tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, is filled with 0.5 to 1 weight % of a non-black insulating pigment that has a heat resistance such that discoloration does not occur when the fluororesin is baked. Green insulating pigment whose main component is a TiO2—CoO—NiO—ZnO system or a ZnO—CoO system, or blue insulating pigment whose main component is a CoO—Al2O3 system or a CoO—Al2O3—Cr2O3 system is used singly or in a combination, as the non-black insulating pigment. A highly arc-resistant insulator is provided that secures an insulating capacity and at the same time that secures an excellent ability to prevent both interior and exterior deterioration of the insulator and that avoids color heterogeneity and localized discoloration.Type: ApplicationFiled: December 29, 2010Publication date: April 28, 2011Inventors: Yoshihiko Hirano, Norimitsu Kato
