Abstract (en)
[origin: DE19914953A1] Emulsion polymerisation of unsaturated monomers for the production of aqueous polymer dispersions is carried out with a radical initiator in presence of a bridged bis-(2-hydroxybenzylidene-amino) metal complex which is more soluble in acid, basic and/or neutral water than in styrene. A radical-initiated aqueous emulsion polymerisation process for the production of aqueous polymer dispersions, in which ethylenically unsaturated monomer(s) is/are dispersed in an aqueous medium and polymerised with the aid of a radical initiator in presence of a metal-organic compound. This metal compound has a structural feature of formula (I): M = a metal ion; Independent claims are included for: (a) aqueous polymer dispersions obtained by this process and containing metal-organic compound(s) (I); and (b) metal-organic compounds with the structural feature (I).
