    摘要: 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.

    摘要: Described herein are amorphous thermoplastic terpolymers containing units of the formula: ##STR1## wherein R is independently hydrogen, C.sub.1 to C.sub.6 alkyl, or C.sub.4 to C.sub.8 cycloalkyl, X' is independently ##STR2## wherein R.sub.1 and R.sub.2 are independently hydrogen or C.sub.1 to C.sub.9 alkyl; ##STR3## wherein R.sub.3 and R.sub.4 are independently hydrogen or C.sub.1 to C.sub.8 alkyl and a.sub.1 is an integer of 2 to 7; --S--, --O--, or ##STR4## a is an integer of 0 to 4 and n is independently an integer of 1 to 3. The units are attached to each other by an --0-- bond. These polymers have an excellent combination of mechanical properties. They display high notched izod impact values, high heat distortion temperatures and excellent environmental stress crack resistance.
