    摘要: An improved process for the production of linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon comprises contacting the carbon monoxide and hydrocarbon under polymerization conditions in the presence of a reaction diluent and a novel catalyst composition formed from a compound of palladium, the anion of a strong non-hydrohalogenic acid and a bis(diethylphosphino)alkane.

    摘要: Linear alternating polymers of carbon monoxide, non-conjugated alkenylbenzene compound and optionally ethylene are produced by contacting the monomeric reactants under polymerization conditions in the presence of an inert reaction diluent and a catalytic quantity of a catalyst composition formed from a compound of palladium, the anion of a strong non-hydrohalogenic acid having a pKa less than 2 and a bis(dialkylphosphino)alkane. The polymer products are thermoplastics and have utility as engineering thermoplastics.

    摘要: An improved process for the production of linear alternating polymers of carbon monoxide and norbornene-type compounds wherein substantially all of the moieties originating from the carbon monoxide are in a spiroketal structure which comprises contacting the carbon monoxide and norbornene compound in a liquid reaction diluent at a temperature below 55.degree. C. in the presence of a catalyst composition formed from a compound of palladium, the anion of a non-hydrohalogenic acid having a pKa below 2, a bidentate ligand of nitrogen and an organic oxidant, the molar ratio of the bidentate ligand to the anion being at least 4.
