The invention relates to a polymer latex made by free-radical emulsion polymerization comprising polymer particles containing structural units derived from at least one conjugated diene component, said polymer particles are at least of 50 ° C. comprising at least one soft phase segment having at least one hard phase segment, and the glass transition temperature of at most be ₁₀ ℃ (T g) having a glass transition temperature (T _g), the hard phase relative to the total weight of the polymer particles the total amount of the portion is 2 to 40 wt%, the total amount of the soft phase segment is the 60-98 wt%, T _g is measured by DSC according to ASTM D3418-03, the polymer latex, measured as the critical coagulation concentration the electrolyte stability (pH 10 with measuring the total solids content of 0.1% latex) is less than _30mmol / l CaCl 2, and more particularly suitable polymer latex for the production of dip-molded articles. Furthermore, the present invention provides a method for producing such a polymer latex, the use of the polymer latex for the production of dip-molded articles, the preferred composite polymer latex composition for the production of dip-molded articles, the manufacturing method of the dip molded latex articles , and to thereby obtain a latex product.
