Publication number: 20230383043Abstract: Disclosed herein is a process of producing a polymeric dispersion by free radical emulsion polymerization of a monomer composition including ethylenically unsaturated monomers in the presence of a block copolymer. The block copolymer has a first block including at least 80 wt.-% units of alkyl acrylate and a second block including units of an ethylenically unsaturated monomer with sulfonic acid groups. Either the first or the second block is connected with a nitroxyl radical. The polymeric dispersion is obtainable by the disclosed process, and the block copolymer is used in the process. Further disclosed herein is a method of using the block copolymer as an emulsifying agent for free radical emulsion polymerization.Type: ApplicationFiled: November 22, 2021Publication date: November 30, 2023Inventors: Crispin AMIRI NAINI, Andreas GERNANDT, Clemens AUSCHRA, Bernd RECK
