Abstract
Abstract Disclosed herein are oriented containers for food, beverages, and medicines wherein the container is the interpolymerization product of A. 65 to 78% by weight of acrylonitrile; B. from 3 to 10% by weight of an alkyl vinyl ether wherein the alkyl group contains from 1 to 2 carbon atoms; C. from 12 to 32% by weight of styrene. These containers exhibit improved toughness and good barrier properties.
