Abstract
An carboxylated nitrile-butadiene rubber latex formulation composed of a blend of a first acrylonitrile terpolymer and a second acrylonitrile terpolymer, wherein: the acrylonitrile content of the blended terpolymers is between 17 and 45% by weight, the methacrylic acid content of the blended termpolymers is less than 15% by weight, and the remaining balance of the terpolymers being butadiene. The invention also includes an elastomeric nitrile rubber article made from the formulation.
