Abstract:
1. A polymer composition comprising: a. about 85 wt % to about 97.5 wt %, based upon the weight of a, and b, of a nitrile-group containing elastomer selected from the group consisting of acrylonitrile-butadiene copolymer rubber, carboxylated acrylonitrile-butadiene copolymer rubber, at least partially hydrogenated acrylonitrile-butadiene copolymer rubber, at least partially hydrogenated carboxylated acrylonitrile-butadiene rubber, and mixtures thereof, wherein the elastomer has: b. about 2.5 wt % to about 7.5 wt %, based upon the weight of a, and b, of a non-functionalized plasticizer (“NFP”), wherein the NFP is a polyalphaolefin derived from C wherein the composition has:
