ABSTRACT OF THE INVENTION POLYAMIDE COMPOSITIONS HAVING NITRILE RUBBER AND COPOLYMER OF ETHYLENE AND ALPHA-OLEFIN THEREIN The present invention is directed to a polyamide composition comprising from about 50 to 90% by weight of a polyamide, from about 10 to 40% by weight of a nitrile rubber, and from about 5 to 50% by weight of a reactive rubber which contains groups of the polyamide. The composition preferably contains about 2 to 20% by weight of a plasticizer for nylon. and can optionally contain from about 0 to 10% by weight of a polyamide chain extender. The present invention also includes gas permeation resistant articles including articles resistant to chlorofluorohydrocarbon permeation. Articles of particular interest include extruded hose and tubing which contain at least one layer made of the above described composition. It has been discovered that the composition of the invention resists chlorofluorohydrocarbon permeation and at the same time can provide the flexibility needed for use in various hose and tubing applications.
