A copolymer, in particular a dispersant for solid particles, in particular a dispersant for mineral binder compositions, including a polymer backbone and sidechains bound thereto. Said copolymer includes at least one phosphorus group-carrying monomeric unit M1 and at least one sidechain-carrying monomeric unit M2, the copolymer having, in a direction along the polymer backbone, a non-random distribution of the monomeric units M1 and/or of the monomeric units M2.
一种共聚物,特别是用于固体颗粒的分散剂,尤其是用于矿物粘结剂组合物的分散剂,包括聚合物主链和与之结合的侧链。所述共聚物包括至少一个含
磷基团的单体单元 M1 和至少一个含侧链的单体单元 M2,共聚物沿聚合物主链方向具有单体单元 M1 和/或单体单元 M2 的非随机分布。
