Abstract
The present invention relates to processes for preparing a copolymer, especially 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 by nitroxide-mediated solution polymerization to give a copolymer, wherein the polymerization is conducted in the presence of an agent comprising a carboxyl group-bearing and phosphated alkoxy amine.
