    Abstract: Polymeric compositions having good impact resistance, low permeability to gases, and high-softening temperatures which are composed of a conjugated diene monomer, such as butadiene, an olefinically unsaturated nitrile, such as acrylonitrile, an alpha-olefin, such as isobutylene, and indene are described.
