    • The present invention relates to the use and application of a water-soluble or water-dispersible copolymer comprising: a) at least a monomer compound of general formula i: in which R1 is a hydrogen atom, a methyl or ethyl group; R2, R3, R4, R5 and R6, which are identical or different, are linear or branched C1-C6, alkyl, hydroxyalkyl or aminoalkyl groups; m is an integer from 0 to 10; n is an integer from 1 to 6; Z represents a —C(O)O— or —C(O)NH— group or an oxygen atom; A represents a (CH2)p group, p being an integer from 1 to 6; B represents a linear or branched C2-C12, polymethylene chain optionally interrupted by one or more heteroatoms or heterogroups, and optionally substituted by one or more hydroxyl or amino groups; X, which are identical or different, represent counterions; and (b) at least one hydrophilic monomer carrying a functional acidic group which is copolymerizable with (a) and which is capable of being ionized in the application medium; (c) optionally at least one monomer compound with ethylenic unsaturation with a neutral charge which is copolymerizable with (a) and (b), preferably a hydrophilic monomer compound with ethylenic unsaturation with a neutral charge, carrying one or more hydrophilic groups, which is copolymerizable with (a) and (b). Said polymer is a particularly good agglomerating agent and can preferentially be used in cleaning operations.
    • 本发明涉及水溶性或水分散性共聚物的用途和应用,其包括:a)至少一种通式I的单体化合物:其中R 1是氢原子,甲基或乙基; R2,R3,R4,R5和R6是相同或不同的直链或支链C1-C6,烷基,羟基烷基或氨基烷基; m为0〜10的整数; n是1至6的整数; Z表示-C(O)O-或-C(O)NH-基或氧原子; A表示(CH 2)p基团,p为1至6的整数; B表示任选地被一个或多个杂原子或杂原子间隔并且任选被一个或多个羟基或氨基取代的直链或支链C 2 -C 12,多亚甲基链; X相同或不同,表示抗衡离子; 和(b)至少一种携带可与(a)共聚的官能酸性基团的亲水性单体,其能够在该涂布介质中离子化; (c)任选地至少一种具有中性电荷的具有烯属不饱和键的单体化合物,其可与(a)和(b)共聚,优选具有带有中性电荷的具有烯属不饱和键的亲水性单体化合物,其携带一个或多个亲水基团, 可与(a)和(b)共聚。 所述聚合物是特别好的附聚剂,并且可以优选用于清洁操作。
