Abstract

Polymer blends of a) polymers containing predominantly mers of (meth)acrylates and/or glutarimides with b) up to about 40 weight percent of polymers having greater than about 50 tool % vinyl alcohol mers exhibit useful barrier properties to oxygen and other environmental gases, while maintaining or enhancing physical properties and clarity.
