Abstract
Linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are hydrogenated in the presence of a catalyst formed from a ruthenium carbonyl and an organic iodide to produce novel alternating polymers wherein one monomeric unit is a two-carbon unit optionally substituted with a methyl group and the other monomeric unit is a 2,5-tetrahydrofurandiyl unit optionally substituted on one of the carbon atoms in the 3 or 4 positions with a methyl group.
