Beschreibung
Zusammenfassung:The present invention relates to processes for the production of polycarboxylate ether copolymers in the solid state, polycarboxylate ether copolymers in the solid state produced thereby, and mineral binder compositions comprising the same. Processes of the invention comprise the steps of providing a first type of monomer, treating the first type of monomer with an acid, providing a second type of monomer, copolymerizing the acid-treated first type of monomer and the second type of monomer to obtain a copolymer which is a polycarboxylate ether, and transferring the copolymer thus obtained into the solid state.
