The present invention provides novel polyesteramides and containers having improved gas barrier properties formed therefrom. The novel polyesteramides comprise the reaction product of a diamine having 2 to about 20 carbon atoms, a diol containing up to about 24 carbon atoms, and a dicarboxylic acid component. The dicarboxylic acid component consists essentially of about 5 to 100 mole % of a specified first, heteroatom-containing dicarboxylic acid, and 0 to about 95 mole % of a second dicarboxylic acid containing up to about 24 carbon atoms. In the polyesteramide, the diamine component comprises about 10 to 90 mole % of the total diamine and diol components. The present invention further provides containers, such as molded containers, films, coextruded articles, laminated articles, etc., formed from the polyesteramides of the present invention. |
