    • The present invention relates to formaldehyde-free aqueous binders for substrates, having a broad molecular weight distribution and comprising (A) from 0 to 100% by weight of an ethylenically unsaturated acid anhydride or ethylenically unsaturated dicarboxylic acid whose carboxylic acid groups can form an anhydride group, or mixtures thereof, (B) from 100 to 0% by weight of an ethylenically unsaturated compound, (C) at least one polyfunctional crosslinker or mixtures thereof, the polymers of A) and B) obtained by free-radical addition polymerization, when classified in a coordinate system by way of their average molecular weight Mw and their polydispersity, being situated in the area above a straight line which is defined by the linear equation y=1.25x+20 000 and has been shifted in y direction parallelwise by at least +3 000, the x axis denoting the weight-average molecular weight and the y axis the polydispersity times 10 000.
    • 本发明涉及用于基材的无甲醛水性粘合剂,其具有宽分子量分布并且包含(A)0至100重量%的烯属不饱和酸酐或烯属不饱和二羧酸,其羧酸基团可以形成酸酐 基团或其混合物,(B)100至0重量%的烯属不饱和化合物,(C)至少一种多官能交联剂或其混合物,通过自由基加成聚合得到的A)和B)的聚合物, 当通过其平均分子量Mw和它们的多分散性分类在坐标系中时,位于由线性方程y = 1.25×+ 20 000定义的直线上方的区域中,并且已经沿y方向平行移位 至少+3000,x轴表示重均分子量,y轴多分散时间为10 000。
