ABSTRACT:
Polymeric compositions having high heat-distortion temperatures which function as gas and vapor barrier materials which are composed of an olefinically unsaturated nitrile, such as acrylonitrile, and indene are produced by the copolymerization of said olefinically unsaturated nitrile and crude indene which can be derived from various sources.
