Abstract
Thermoplastic resins of enhanced solvent resistance especially useful for packaging or automotive parts comprising blends of amorphous polyamides with a thermoplastic polyester resin, substantially free of a polyarylate have excellent physical properties and barrier resistance to oxygen and carbon dioxide. Preferred blends comprise polyesters prepared by reacting a dihydric alcohol with a dicarboxylic acid, and amorphous polyamides prepared from non-symmetric monomers comprising odd-number chain diamines and diacids, and meta aromatic diamines and diacids.
