VERNETZBARE POLYMERZUSAMMENSETZUNG AUS ZWEI MITEINANDER REAKTIVEN COPOYLMERISATEN UNTERSCHIEDLICHER GLASSÜBERGANGSTEMPERATUREN
The invention relates to a crosslinkable polymer composition in the form of an aqueous polymer dispersion or a polymer powder, containing A) a mixed polymerisate of one or more comonomers a1) from the group containing vinyl esters of unbranched or branched alkyl carboxylic acids with 1 to 18 C atoms, acrylic acid esters, and methacrylic acid esters of branched or unbranched alcohols with 1 to 15 C atoms, dienes, olefins, vinyl aromatics, and vinyl halides, and 0.1 to 30 wt.%, based on the total weight of the comonomers, of one or more ethylenically unsaturated functional comonomers a2, which contain carboxyl, hydroxy, or NH groups, and B) a mixed polymerisate of one or more comonomers b1) from the group containing vinyl ester or unbranched or branched alkyl carboxylic acids with 1 to 18 C atoms, acrylic acid esters, and methacrylic acid esters of branched or unbranched alcohols with 1 to 15 C atoms, dienes, olefins, vinyl aromatics, and vinyl halides, and 0.1 to 30 wt.%, based on the total weight of the comonomers, of one or more ethylenically unsaturated functional comonomers b2) which can react with the functional groups of the comonomers a2 ) and which contain epoxy, N-methylol, or isocyanate groups. The invention is characterized in that one of the mixed polymerisates A) or B) has a glass transition temperature Tg of less than 30 °C and the respective other mixed polymerisate A) or B) has a glass transition temperature Tg of more than 50 °C.
