    摘要: Metal complexes having general formula (I) are useful to copolymerise carbon monoxide with olefinically unsaturated compounds. In said formula, the substituents and indexes have the following meanings: M is a metal of group VIIB of the periodic table of elements; E1, E2 stand for an element of group VA of the periodic table of elements; Z stands for a structural unit with a bridging atom selected among the elements of groups IVA, VA or VIA of the periodic table of elements; R1 to R4 stand for substituents selected in the group that consists of C¿1?-C20 organic carbon residues and C3-C30 organic silicium residues and at least one of these four residues is a non-aromatic residue; L?1, L2¿ stand for formally charged or neutral ligands; X stand for monovalent or polyvalent anions; p equals 0, 1 or 2; m, n equal 0, 1 or 2, whereas p = m x n.

    摘要: The invention concerns copolymers of carbon monoxide with olefinically unsaturated compounds, obtainable by polymerisation of the monomers in the presence of a metal complex of general formula (I) in which the substituents and indices have the following meanings: M is a group VIIIB metal; E1, E2 are a group VA element; Z is a structural unit with a bridging atom selected from among the group IVA, VA or VIA elements; R1-R4 are substituents selected from the group comprising C¿1?-C20 carbon-organic and C3-C30 silicon-organic rests, at least one of the four rests beins a non-aromatic rest; L?1, L2¿ are formally charged or neutral ligands; X stands for formally mono- or polyvalent anions; p is 0, 1 or 2, m and n are 0, 1 or 2, and p = m x n.
