Document Type and Number:
Japanese Patent JPH11507966
Kind Code:
A
Abstract:
A catalyst composition which is based upon (a) a source of nickel cations, and (b) a bidentate ligand of the general formula R1R2M1-R-M2R3R4(I) wherein M1 and M2 represent independently phosphorus, nitrogen, arsenic or antimony, R1, R2, R3 and R4 represent independently optionally polar substituted hydrocarbyl groups on the understanding that at least one of R1, R2, R3 and R4 represent a substituted aryl group, and R represents a bivalent bridging group of which the bridge consists of at most two bridging atoms, and a process for the preparation of copolymers of carbon monoxide and an olefinically unsaturated compound comprising ontacting the monomers in the presence of the said catalyst composition.
