  • Publication number: 20170073449
    Abstract: A block copolymer, in particular for use as a dispersant for mineral binder compositions, including at least one first block A and at least one second block B, wherein the first block A has a monomer unit M1 and the second block B has a monomer unit M2. To this end a proportion of monomer units M2 which is in any case present in the first block A is less than 25 mol %, in particular less than or equal to 10 mol %, based on all the monomer units M1 in the first block A and a proportion of monomer units M1 which is in any case present in the second block B is less than 25 mol %, in particular less than or equal to 10 mol %, based on all the monomer units M2 in the second block B.
