Abstract
A glove is formed from elastomer having Mooney viscosity, ML(100° C.) of 100-220, that contains 25-30 weight % of acrylonitrile, 62-71 weight % of butadiene and 4-8 weight % of unsaturated carboxylic acid, and does not contain sulfur crosslinking agents or vulcanization accelerators. The unsaturated carboxylic acid comprises a first fraction of substituents and a second fraction of substituents, the first fraction of substituents forming cross-links via bonds with each other, and the second fraction of substituents forming cross-links via bonds with a bivalent metal. Glove properties include thickness 0.05-0.15 mm, swelling ratio 240-320, tensile stress 22-35 MPa, elongation to break 480-620%, and tensile stress at 500% elongation 15-35 MPa. By chlorine treatment of both inner and outer surfaces of the glove, the inner surface has decreased tackiness and the outer surface has increased smoothness. Content of metal and metallic salt impurities and an anion contained in the glove is decreased.
