The present invention relates to carboxylated butadiene nitrile latex, used for manufacturing of the dip-molded articles, in particular for production of latex gloves for industrial and medical purpose. More particular, the present invention relates to a latex for the manufacture of the dip-molded articles, comprising structural units formed from at least one monomer which is conjugated diene, at least one ethylene unsaturated monomer comprising a nitrile group, and at least one monomer which is an unsaturated carboxylic acid, where the value of the solubility index (A), calculated by the formula А=100 * p *S /(Mn+Mw) is 0.5 to 22 wt%*nm*mol*g-1, where p is polymer solubility in methyl ethyl ketone (wt%), S - latex particle size (nm), Mn – number-average molecular weight of the tetrahydrofuran-soluble fraction of butadiene-nitrile latex (g/mol), Mw is weight average molecular weight of the tetrahydrofuran-soluble fraction of butadiene-nitrile latex (g/mol), with the polydispersity value of latex polymer Mw/Mn of 2.0 to 5.0. The present invention also relates to a dip-molding composition based on butadiene-nitrile latex, to a dip-molded article and to a glove, manufactured based on the latex composition according to the present invention.
