T 1462 A B S T R A C T CATALYST COMPOSITIONS AND POLYMERIZATION PROCESS, HEXAKISPHOSPHINES AND HEXAHALO COMPOUNDS Catalyst compositions which contain a Group VIII metal and a hexakisphosphine of the general formula (R1R2P)6R5 in which R1 and R2 represent identical or different optionally polar-substituted hydrocarbyl groups and in which R5 is a hexavalent organic linking group which connects the six phosphorus atoms, are suitable for the preparation of copolymers of carbon monoxide and olefinically unsaturated compounds. Certain intermediates useful for their preparation are novel compounds. MK1/T1462FF
