    • The use of water-soluble, amphoteric copolymers which are obtainable by copolymerization of a) at least one N-vinylcarboxamide of the general formula in which R1 and R2, independently of one another, are H or C1- to C6-alkyl, b) at least one monomer which is selected from the group consisting of (b1) monoethylenically unsaturated sulfonic acids, phosphonic acids, phosphoric acid esters and derivatives thereof, and (b2) monoethylenically unsaturated mono- and dicarboxylic acids, the salts thereof and dicarboxylic anhydrides, c) if appropriate, at least one monoethylenically unsaturated monomer differing from the components (a) and (b), and d) if appropriate, at least one compound which has at least two ethylenically unsaturated double bonds in the molecule, with the proviso that the monomer mixture comprises at least one monomer (b) having at least one free acid group and/or an acid group in salt form,and subsequent partial or complete hydrolysis of the groups —CO—R1 from the monomers (a) incorporated in the form of copolymerized units into the copolymer,as agents for increasing the initial wet web strength of paper.
    • 通过使a)至少一种通式的N-乙烯基甲酰胺与其中R 1和R 2彼此独立地是H或C 1至C 6烷基的共聚获得的水溶性两性共聚物的用途,b) 至少一种选自(b1)单烯键式不饱和磺酸,膦酸,磷酸酯及其衍生物的单体和(b2)单烯属不饱和单羧酸和二羧酸,其盐和二羧酸酐,c )如果合适,至少一种不同于组分(a)和(b)的单烯属不饱和单体,和d)如果合适,至少一种在分子中具有至少两个烯属不饱和双键的化合物,条件是 单体混合物包含至少一种具有至少一种盐形式的游离酸基团和/或酸基团的单体(b),随后从单体部分或完全水解基团-CO-R1 (a)以共聚单元的形式引入共聚物中,作为用于增加纸的初始湿纸幅强度的试剂。
