Zusammenfassung: | A polymeric surfactant being a block copolymer comprising chemically linked polymeric blocks (a) and (b), the block (a) part of said copolymer consisting of homo- or copolymerized apolar monomeric Alpha, Beta-ethylenically unsaturated compound(s), characterized in that the block (b) part of said copolymer consists of polymerized Alpha,Beta-ethylenically unsaturated monomer containing an epoxy group that has been transformed into an ionic group. The use of said surfactant as dispersing agent in aqueous dispersions and plasticizing agent in hydrophilic colloid layers. |
