Abstract: Method for preparing aqueous polymer dispersions (A) by polymerizing at least one olefin, optionally also carbon monoxide, in aqueous medium, in presence of a metal complex (I) and one or more dispersants. Method for preparing aqueous polymer dispersions (A) by polymerizing at least one olefin, optionally also carbon monoxide, in aqueous medium, in presence of a metal complex of formula (I) and one or more dispersants. M = transition metal of groups VIIIB, IB or IIB; E1 and E2 = group VA atoms; Y = 1-6C alkylene (optionally substituted by hydroxy, 1-6C alkoxy, carboxy, sulfo, amino, ammonium, phosphono, phosphonato, sulfamoyl, amidino, carbamoyl, hydroxysulfonyloxy, sulfino or 1-4C alkyl, or interrupted by oxygen, imino, silylene, or mono- or di-alkylsilylene), a fused cycloaliphatic ring or benzene ring, or 1,8-naphthylene; R1 = 1-20C alkyl (optionally substituted by hydroxy, 1-6C alkoxy, carboxy, sulfo or aryl), 6-14C aryl (optionally substituted by 1-4C alkyl, hydroxy, 1-6C alkoxy, carboxy, cyano or R2) or 3-12C cycloalkyl; R2 = fluoro, sulfo, nitro or 1-10C perfluoroalkyl; R3-R6 = hydrogen or R2; L1 and L2 = (R7)xPH3-x, (R7)xNH3-x, R7OR7, R7OH, water, pyridine substituted by x R7, CO, 1-14C alkyl nitrile, 6-12C aryl nitrile, olefin, (R7)hNH2-h, or anions of 1-6 C alkyl, 3-14C cycloalkyl, (meth)allyl, benzyl, aryl, carboxylic or sulfonic acids, or (di)ketones, optionally linked by one or more covalent bonds; x = 0-3; h = 0-2; R1 = hydrogen, 1-20C alkyl (optionally substituted by 1-6C alkoxy, mono- or di-(1-6C alkyl) amino or 6-14C aryl), 3-12C cycloalkyl or 6-14C aryl; An- = an equivalent of an anion of a non-coordinating acid with pKa less than 4.75; and n = 0-4 Independent claims are also included for the following: (1) aqueous dispersions produced by the new method, having head-to-tail content below 90% and mean particle size 1 mum; and (2) method for preparing polyketones (II) by isolation from (A).
