ABSTRACT:
Novel, linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon have a high degree of monomeric unit purity. The polymers, produced with a catalyst composition formed from preformed palladium trifluoroacetate and a bidentate phosphorous ligand, exhibit improved thermal stability and enhanced crystallinity and crystallizability.
