Abstract: RUBBER-MODIFIED ACRYLONITRILLE-VINYL ETHER-INDENE POLYMERS Polymer resins which are impact resistant, have high flexural strengths, are relatively high softening and function as gas and vapor barrier materials are composed of an olefinically unsaturated nitrile, such as acrylonitrile, a vinyl ether, such as butyl vinyl ether, indene and a conjugated diene rubber, such as an acrylonitrile-butadiene copolymer.
