<p>A copolymer latex is provided which comprises 30 to 90 % by weight of a conjugated diene monomer unit, 9 to 50 % by weight of an ethylenically unsaturated nitrile monomer unit, 0.1 to 20 % by weight of an ethylenically unsaturated acid monomer unit and 0 to 20 % by weight of an other ethylenically unsaturated monomer unit copolymerizable therewith, having a polystyrene-converted weight average molecular weight of 50,000 to 500,000, and containing 45 % or less of methyl ethyl ketone insoluble matter. The latex is presented by emulsion polymerization using a polymerization initiator containing a peroxide whose decomposition temperature giving a half-life period of 10 hours is 100 DEG C or higher and a reducing agent. The latex is used advantageously for dip molding.</p> |
