Abstract
The invention is a process for preparing a linear alternating polymer which process comprises contacting ethylene and carbon monoxide in the presence of a catalyst, at a total pressure within the range of 100 to about 250 bar and an ethylene/carbon monoxide partial pressure ratio from about 0.75 to about 3, wherein the catalyst comprise (1) a Group VIII metal compound of palladium, cobalt or nickel, (2) an anion of a non-hydrohalogenic acid with a pKa less than 6 and (3) a bidentate phosphorus, arsenic or antimony ligand.
