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.

Claim (Index 4):
The copolymer as claimed in  claim 1 , wherein the phosphorus group-bearing monomer unit M1 in the copolymer has a structure of the formula I and the side chain-bearing monomer unit M2 includes a structure of the formula II where R 1 , in each case independently, is a group of the formula Ia and L has a structure of the formula (Ib) with a=0-5; b=0 or 1; c=0 or 1; d=0-5; e=0 or 1; f=1-10; g=0-5; h=1-5; i=0 or 1; j=0 or 1; and where G is \u2014O\u2014 or \u2014NH\u2014; and each Q, independently of the others, is hydrogen, an alkyl group having 1-5 carbon atoms and/or PO 3 M 2 ; each K, independently of the others, is hydrogen, a chemical bond or an alkylene group having 1-3 carbon atoms; R 2 , R 3 , R 5  and R 6 , in each case independently, are H or an alkyl group having 1 to 5 carbon atoms, R 4  and R 7 , in each case independently, are H, \u2014COOM or an alkyl group having 1 to 5 carbon atoms, or where R 1  forms a ring together with R 4  to give \u2014CO\u2014O\u2014CO\u2014, M, independently of one another, represents H +  an alkali metal ion, an alkaline earth metal ion, a di- or trivalent metal ion, an ammonium ion or an organic ammonium group; m=0, 1 or 2, p=0 or 1, X, in each case independently, is \u2014O\u2014 or \u2014NH\u2014, R 8  is a group of the formula -[AO] n \u2014R a  where A=C 2 - to C 4 -alkylene, R a  is H, a C 1 - to C 20 -alkyl group, -cycloalkyl group or -alkylaryl group, and n=2-250.
