ABSTRACT:
A blend of 5 to 95 percent of an ethylene vinyl alcohol copolymer and 95 to 5 percent of an amorphous polyamide having fewer than about 0.100 equivalents of carboxyl end groups per kilogram of polyamide exhibits improved oxidative and thermal stability. The blend is useful for preparing films and multiple layered structures including thermoformed structures and oriented shrink films.
