  • Patent number: 11111364
    Abstract: A polymer composite material includes a blend of one or more thermoplastic polymers and one or more bio-based flame retardant additives, wherein the one or more bio-based flame retardant additives are present in an amount of 35 to 100 parts per 100 parts by weight of the one or more thermo-plastic polymers. A method of forming the polymer composite material includes: blending the one or more thermoplastic polymers and the one or more bio-based flame retardant additives together at a temperature between 140° C. and 230° C. to form the polymer composite material; forming an article from the polymer composite material; and cooling the formed article.
    Type: Grant

  • Publication number: 20060246245
    Abstract: 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.
