Beschreibung
Zusammenfassung:	The invention concerns a polycondensate containing (I) at least a structural unit, which is an aromatic moiety bearing a polyether side chain comprising 9 to 41 alkylene glycol units, (II) at least a structural unit, which is an aromatic moiety bearing at least one phosphoric acid ester group and (III) at least a methylene unit (-CH2-), the polycondensate having a polycondensation degree of 10 to 75. Also concerned are building material mixtures containing said polycondensates and the use as dispersant for inorganic binders. 本发明涉及种缩聚物，其包含：(I)至少种结构单元，其为带有含有9至41个烷撑二醇单元的聚醚侧链的芳族部分；(II)至少种结构单元，其为带有至少个磷酸酯基团的芳族部分；以及(III)至少个亚甲基单元(-CH-)，所述缩聚物的缩聚度为10至75。本发明还涉及含有所述缩聚物的建筑材料混合物以及用作无机胶粘剂的分散剂的用途。
