    • Comb polymers having carboxyl/carboxylate and ester groups, containing a) 0.1-0.9 mol fractions of a partial structural unit S1, which is derived from an acrylic/methacrylic or maleic acid unit, b) 0-0.4 mol fractions of a partial structural unit S2, which is derived, for example, from an acrylic/methacrylic or maleic acid unit, which is esterified by means of a C1 to C20-alkanol or a polyalkylene glycol, alkyl-capped on one end, preferably a polyethylene glycol, and c) 0.1-0.4 mol fractions of a partial structural unit S3, which is derived from an acrylic/methacrylic or maleic acid unit, which is esterified by means of a polyalkylene glycol monoalkyl ether, which has a terminal, secondary hydroxyl group of the form-CH(R3)OH, wherein R3 is bulky alkyl group, preferably a methyl group.
    • 具有羧基/羧酸酯和酯基的梳理聚合物,其包含a)0.1-0.9摩尔部分结构单元S1的部分,其衍生自丙烯酸/甲基丙烯酸或马来酸单元,b)0-0.4摩尔部分结构单元 S2,其衍生自例如丙烯酸/甲基丙烯酸或马来酸单元,其通过C1至C20链烷醇或聚亚烷基二醇酯化,一端烷基封端,优选聚乙二醇,c )0.1-0.4摩尔部分结构单元S3,其衍生自丙烯酸/甲基丙烯酸或马来酸单元,其通过聚亚烷基二醇单烷基醚酯化,所述聚亚烷基二醇单烷基醚具有末端的形成羟基的仲羟基, CH(R3)OH,其中R3是大体积烷基,优选甲基。
