A process for preparing a copolymer composition A) by free-radical copolymerization of a monomer composition comprising: a) acrylic acid, b) optionally at least one compound, different from a), having a free-radically polymerizable, α,β-ethylenically unsaturated double bond and at least one anionogenic and/or anionic group per molecule, c) at least one free-radically polymerizable crosslinking compound which comprises at least two α,β-ethylenically unsaturated double bonds per molecule. The process is performed by precipitation polymerization in the presence of an auxiliary composition H) comprising H1) glycerol monostearate, and H2) at least one compound with an HLB value in the range from 4 to 10, selected from water-insoluble natural waxes, nonionic emulsifiers and mixtures thereof.
一种制备共聚物组合物A的方法,包括以下步骤:A)通过自由基共聚合反应制备单体组合物,所述单体组合物包括:a)丙烯酸,b)选择性地至少包括一种与a)不同的化合物,其具有自由基聚合能力的α,β-乙烯基不饱和双键和至少一个分子中的阴离子和/或阴离子基团,c)至少包括一种自由基聚合交联剂,其包括每个分子中至少两个α,β-乙烯基不饱和双键。该方法通过在辅助组成物H的存在下进行沉淀聚合反应,所述辅助组成物H包括H1)单硬脂酸甘油酯,和H2)HLB值在4到10范围内的至少一种化合物,所述化合物选自不溶于水的天然蜡、非离子乳化剂和它们的混合物。
