  Copolymers that comprise salicylic acid derivative structural units and structural units having free polyether side chains. The copolymers are suitable to plasticize inorganic binder systems, construction chemical compositions comprising the copolymers and the use of the copolymers as a plasticizer for inorganic binder systems. Binder systems with a reduced amount of Portland cement comprising at least one copolymer of the invention provide a better liquefaction and processability as compared to the binder systems without a copolymer of the invention.

  由水杨酸衍生物结构单元和具有游离聚醚侧链的结构单元组成的共聚物。这些共聚物适用于无机粘结剂体系的塑化、包含共聚物的建筑化学组合物，以及将共聚物用作无机粘结剂体系的增塑剂。与不含本发明共聚物的粘结剂体系相比，含至少一种本发明共聚物的硅酸盐水泥用量减少的粘结剂体系具有更好的液化性和可加工性。

  The present invention relates to copolymers that comprise salicylic acid derivative structural units and structural units having free polyether side chains. The copolymers are suitable to plasticize inorganic binder systems, construction chemical compositions comprising said copolymers and the use of said copolymers as a plasticizer for inorganic binder systems. Binder systems with a reduced amount of Portland cement comprising at least one copolymer of the invention provide a better liquefaction and processability as compared to said binder systems without a copolymer of the invention.
