Abstract
An emulsion composition for producing a glove, the composition containing: (1) a carboxylated acrylonitrile-butadiene elastomer, comprising 30 to 40% by weight of acrylonitrile residues and 3 to 8% by weight of unsaturated carboxylic acid residues, having an elemental sulfur content detected by neutralization titration of a combusted product of the elastomer of not more than 1% by weight of the elastomer weight, and having a Mooney viscosity (ML(1+4) (100° C.)) of 100 to 220, and (2) a poly(acrylonitrile-butadiene) having a styrene-equivalent weight-average molecular weight of 7,000 to 500,000, wherein the weight ratio of component (1)/component (2) is from 70/30 to 90/10. Also provided is a glove which, as a result of comprising the emulsion composition, exhibits excellent chemical resistance and superior flexibility.
