Abstract: 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).

Abstract: The coating agents comprise an additive and product obtained by reacting a monomer in the presence of an initiator and a specified ethylenic compound. A coating agent contains at least one reaction product (A) and at least one additive (C), in which (A) is obtained by reacting a radical polymerizable monomer (a) in an aqueous phase in the presence of a radical initiator, and a compound of formula (I): R1-R4 = H, optionally substituted alkyl, cycloalkyl, aromatic hydrocarbon, with the proviso that at least two of R1 to R4 = optionally substituted hydrocarbon. Independent claims are included for: (1) A coating containing (A) and (C) and at least one polymer (B) obtained by reaction of (A) under radical conditions in the presence of at least one radically homo- or copolymerizable monomer (b); (2) a process for coating substrates using the coating agents described.

Abstract: N-oxyl radicals derived from 5-morpholone derivatives substituted at positions 2 and 6 with four organic groups, possibly combined with the linking carbons to form at least 3-membered spiro rings. N-oxyl radicals of formula (I): R -R = organic residues, which may be combined in pairs (R /R and/or R /R ) together with the linking carbons to form rings with at least 3 atoms. Independent claims are also included for: (a) N-oxyl radical formers which produce (I) as a fragment by homolytic cleavage of a chemical bond; (b) a process for the radically initiated polymerisation of olefinically unsaturated monomers in presence of (I); (c) a composition containing unsaturated monomer(s) and (I) and/or radical formers as in (a); (d) a method for the stabilization of unsaturated monomer-containing compositions against unwanted polymerisation by the addition of (I).
