    摘要: 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 (Tg) of at least 50° C. and at least one soft phase segment having a glass transition temperature (Tg) of 10° 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 Tg 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 CaCl2 (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.

    摘要: A radiation curable hot-melt adhesive is provided which contains a polyurethane polymer. This polyurethane polymer is prepared from A) a reactive polyurethane prepolymer which contains at least two NCO groups, B) a low molecular weight compound which comprises a free-radically polymerizable double bond and a functional group which reacts with a NCO group; C) a compound which comprises a functional group which reacts with a NCO group, but does not comprise a functional group polymerizable under free-radical condition; and D) a free-radical photoinitiator which contains a primary or secondary alcohol functional group. The radiation curable hot-melt adhesive is suitable as tapes, films, labels or articles for medical use with pressure-sensitively adhesive layers, in particular, for adhesively bonding shrinkable labels on rotationally symmetrical containers.
