Title:
Production of dispersants by living radical polymerization

"The core of the invention is accordingly a process for preparing a dispersant for solid particles, in particular a dispersant for mineral binder compositions, wherein ionizable monomers m1 and side chain-bearing monomers m2 are polymerized to give a copolymer, the process having the feature that the polymerization is effected by a 'living free-radical polymerization'."
"As has been shown, it is possible by a 'living free-radical polymerization' to effectively calculate, modify and/or control the polymer structure, and the sequence of the polymer units."
