Abstract
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.
