Metal complexes of iminohydroxamic acids are new. Metal complexes (I) of iminohydroxamic acids of formulae (1a) or (1b) are claimed. Nu = O, S, NR4, PR4; M = Ti, Zr, Hf, V, Nb, Ta, Cr, Ni, Pd; h = 0-4; y = oxidation state of M minus 1; z=oxidation state of M minus 2; X = halo, 1-6C alkoxy, acetylacetonate, (N(R5R6), 1-8C alkyl, 3-12C cycloalkyl, 7-13C aralkyl or 6-14C aryl; R1, R4 = H, optionally substitued 1-18C alkyl, optionally substittuted 2-18C alkenyl having 1-4 isolated or conjugated double bonds, optionally substituted 3-12C cycloalkyl, 7-13C aralkyl, 6-14C aryl optionally substituted with optionally substitiuted 1-18C alkyl or 2-18C alkenyl, 3-12C cycloalkyl, 7-13C aralkyl, 6-14C aryl, halo, optionally substituted 1-6C alkoxy, 6-14C aryloxy, SiR5R6R7, 5-6 membered nitrogen containing heteroaryl groups, optionally substituted with 1-18C alkyl or 2-18C alkenyl, 3-12C cycloalkyl, 7-13C aralkyl, 6-14C aryl, halo, 1-6C alkoxy, 6-14C aryloxy, SiR5R6R7; R2 = optionally substituted 6-14C aryl or a 5-6 membered nitrogen containing heteroaryl, optionally substituted as above; R3 = optionally substituted 1-18C alkyl, optionally substituted 2-18C alkenyl having 1-4 isolated or conjugated double bonds, optionally substituted 3-12C cycloalkyl, 7-13C aralkyl, optionally substituted 6-14C aryl, optionally substituted 5-6 membered nitrogen containing heteroaryl whereby neighboring R1-R4 groups are optionally bonded to form 5-12 membered rings optionally substituted by 1-8C alkyl or 2-8C alkenyl having 1-4 isolated or conjugated double bonds, 3-12C cycloalkyl, optionally substituted 7-13C aralkyl or 6-14C aryl; L1 = (in)organic neutral ligand; R5-R7 = H, 1-8C alkyl, 3-12C cycloalkyl, 7-13C aralkyl or 6-14C aryl Independent claims are included for: (i) a process for the (co)polymerization of olefins and/or styrene using the complexes (I); (ii) a process for the production of polyolefin waxes using the complexes (I) and a regulator, preferably hydrogen; (iii) a process for the production of the complexes (I) by deprotonation of a protonated ligand of formula (2) by means of a base followed by reaction with a metal compound of formula MXy+1 (3), optionally stabilized by neutral ligands; (iv) a process for the production of supported catalysts for the (co)polymerization of olefins by deposition of a complex (I) and optionally an activator onto a solid support; (v) the resulting supported catalyst; (vi) a process for the emulsion (co)polymerization of ethylene or other 1-olefins and optionally other olefins using the complex (I).
