Title
(EN) Polymer latex suitable for the preparation of dip-molded articles
(ZH) 适合于制备蘸塑制品的聚合物胶乳
Abstract
(EN)
The present 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, whereby said polymer particles comprise at least one hard phase segment having a glass transition temperature (T<SUB>g)</SUB> of at least 50 DEG C and at least one soft phase segment having a glass transition temperature (T<SUB>g</SUB>) of 10 DEG C at most, the total amount of hard phase segments being 2 to 40 wt-% and the total amount of the soft phase segments being 60 to 98 wt-% based on the total weight of the polymer particles, whereby the T<SUB>g</SUB> is measured by DSC according to ASTM D3418-03 and said polymer latex having an electrolyte stability determined as critical coagulation concentration of less than 30 mmol/l CaCl<SUB>2</SUB> (determined for a total solids content of the latex of 0.1% at pH 10) that is particularly suitable for the production of dip-molded articles. Furthermore, the present invention relates to a process for making such a polymer latex, to the use of said polymer latex for the production of dip-molded articles, to a compounded polymer latex composition that is suitable for the production of dip-molded articles, to a method for making dip-molded latex articles, as well as to the latex articles obtained thereby.
