摘要:
Catalyst systems suitable for preparing polyketones consist of: (a) a compound of a metal of the 8th sub-group of the periodic system; (b) a protonic acid and a Lewis acid; and (c) a biphosphine having general formula (I), in which R?1 and R3¿ stand for cycloaliphatic or branched aliphatic residues and R?2 and R4¿ also stand for such residues or for non-branched aliphatic residues, whereas the C atoms in the residues R1-R4 may be substituted by heteroatoms.
