Japanese Patent JP2004534896

A

A process for preparation of aqueous copolymerizate dispersions from copolymerizates of carbon monoxide and olefinically unsaturated compounds by copolymerization of carbon monoxide and the olefinically unsaturated compounds in aqueous medium in the presence of metal complexes. A process for preparation of aqueous copolymerizate dispersions from copolymerizates of carbon monoxide and olefinically unsaturated compounds by copolymerization of carbon monoxide and the olefinically unsaturated compounds in aqueous medium in the presence of:- (a) metal complexes of formula (I), (b) a dispersion agent and optionally (c) a slightly water-soluble organic solvent. G = -(CRb2)r-, -(CRb2)s-Si(Ra)2-(CRb2)t-, -A-O-B- or -A-Z'(R<5>)-B-; R<5> = H, 1-20C alkyl, 3-10C cycloalkyl, 6-14C aryl, with functional groups based on groups IVA, VA or VIIA non-metallic elements, substituted 6-14C aryl, aralkyl with 1-20C alkyl and 6-14C aryl parts, heteroaryl, a long chain 5-30C residue, which has polar or charged end groups -N(Rb)2 and -Si(Rc)3 available, or a residue of formula (II) q = 0-20; A, B = an r'-, s-, or t-atomic component of a ring system, or, together with Z', a (r'+1)-, (s+1)- or (t+1)-atomic component of a heteroring; Ra = 1-20C alkyl, 3-10C cycloalkyl, 6-14C aryl, with functional groups based on groups IVA, VA or VIIA non-metallic elements, substituted 6-14C aryl, or aralkyl with 1-20C in the alkyl part and 6-14C in the aryl part; Rb = as Ra, and additionally H and -Si(Rc)3; Rc = 1-20C alkyl, 3-10C cycloalkyl, 6-14C aryl, or aralkyl with 1-20C in the alkyl part and 6-14C in the aryl part; r = 1-4; r' = 1 or 2; s, t = 0-2 provided that 1 <= s+t <= 3; Z' = a group VA element; M = a metal selected from groups VIIIB, IB, or IIB; E<1>, E<2> = a non-metallic element from group VA; R<1>-R<4> = 1-20C alkyl, 3-10C cycloalkyl, 6-14C aryl with functional groups based on groups IVA, VA or VIA, or VIIA non-metallic elements, substituted 6-14C aryl, aralkyl with 1-20C alkyl in the alkyl part and 6-14C in the aryl part, or heteroaryl; L<1>, L<2> = formally charged or neutral ligands; X = mono- or multivalent anion; p, m, n = 0-4 and p = m \* n or a compound of formula (III) Rd-Rg = H or optionally branched 1-6C alkyl, or Re and Rf together = a 5- or 6-membered carbocyclic or hetero ring. The metal complex (a) is partially or wholly dissolved in the total amount of the olefinically unsaturated compounds and/or the organic solvent (c). Part or all of the olefinically unsaturated compounds and/or the organic solvent (c), in which the metal complex is dissolved , are present in the aqueous medium as disperse phase, with a mean drop diameter of <= 1000 nm. An Independent claim is also included for an aqueous copolymerizate dispersion prepared as above.
