发明名称 Polyamide resin capable of forming containers having improved gas barrier properties from phenylene dioxy diacetic acid and naphthalene dicarboxylic acid
摘要 The present invention provides polyamide resins useful for forming containers having improved resistance to gas permeability. The containers are formed from a polyamide resin which comprises the reaction product of a diamine containing 2 to about 10 carbon atoms and a diacid component which comprises about 25 to 95 mole percent of a first diacid selected from 1,4-phenylenedioxy diacetic acid, 1,3-phenylenedioxy diacetic acid, 1,2-phenylenedioxy diacetic acid, and mixtures thereof, and about 5 to about 75 mole percent of a naphthalene dicarboxylic acid. The polyamide resin has an inherent viscosity of about 0.5 to 1.5. The containers which are provided by the present invention may be in the form of sheet, film, molded articles, such as bottles, and other such structures.
