    摘要: A catalyst composition for preparing polyketones comprises (a) a Group VIII metal compound, containing at least one ligand capable of coordinating to the Group VIII metal and, (b) a compound of the formula BXYZ where at least one of X, Y and Z is a chloro or bromophenyl group preferably B(p-ClC.sub.6 H.sub.4).sub.3. Polyketones having p-chlorophenyl or p-bromophenyl end groups are also disclosed.
