24-51(7564)A ELASTOMERIC BLENDS ABSTRACT Compositions of acrylic rubber and another rubber which can be nitrile rubber, hydrogenated nitrile rubber, fluoroelastomer, silicone rubber, or fluorosilicone rubber are described, in which the acrylic rubber can be uncured or at least partially crosslinked. The compositions are millable and processable and, by the addition of curatives for the nitrile rubber, hydrogenated nitrile rubber, fluoro- elastomer, silicone rubber, or fluorosilicone rubber, can be further crosslinked to become vulcanizates which exhibit excellent resistance to the effects of hot air, hot oil, and ozone. The acrylic rubber is a copolymer from alkyl acrylate monomer which copolymer contains no crosslinking sites other than acrylate ester sites, and can be crosslinked by reaction with a paraffinic alcohol.
