【発明の名称】一酸化炭素とエチレン性不飽和化合物の共重合体の調製方法
Document Type and Number:
Japanese Patent JPH07507089
Kind Code:
A
Abstract:
A process for the preparation of copolymers which comprises reacting carbon monoxide and one or more ethylenically unsaturated compounds under polymerization conditions in the presence of a catalyst system comprising: (a) at least one metal selected from the Groups VI, VII and/or VIII of the Periodic Table; and (b) a stabilizing organic compound attached to (one of) the said metal(s) and containing at least one group capable of forming an additional, non-covalent, bond with (one of) the said metal(s). Also disclosed are products made by the process of the invention, and novel complexes of the general formula [LPdQ] [A]n, wherein Q stands for 2-acylnorborn-1-yl, 2-acylnorborn-3-en-1-yl or a 2-acylethyl group, n is 0 or 1, A stands for a weakly or non-coordinating anion and, if n is 1, L stands for bidentate ligand of the general formula R1R2M1-R-M2R3R4, wherein R1, R2, R3, and R4 independently represent substituted or nonsubstituted hydrocarbyl groups, M1 and M2 independently represent phosphorus, arsenic, antimony or nitrogen and R represents a divalent organic bridging group containing at least one carbon atom in the bridge, or, if n =0, L stands for a sulfonate anion of the general formula R8R9P-R10-SO-3 wherein R8 and R9 independently represent substituted or non-substituted hydrocarbyl groups and R10 represents an organic bridging group having 1-4 carbon atoms in the bridge.
