    摘要： Certain linear alternating polymers of carbon monoxide and aliphatic .alpha.-olefin of 3 or more carbon atoms are characterized by a high degree of stereoregular character. Reduction of the degree of this stereoregular character, whether syndiotactic or isotactic, is achieved together with an increase in atactic character by contacting the stereoregular polymer with organic base at elevated temperature.

    摘要： Novel linear alternating copolymers of carbon monoxide and a 1,2-alkadiene are produced by contacting the carbon monoxide and alkadiene under polymerization conditions in the presence of a catalyst composition formed from a palladium compound, the anion of a non-hydrohalogenic acid having a pKa less than 4 and a bidentate ligand of nitrogen. The novel copolymers are formed in a mixture with linear alternating copolymer of carbon monoxide and ethylenically unsaturated hydrocarbon when an ethylenically unsaturated hydrocarbon is additionally present in the polymerization mixture.

C. and about 245.degree. C. The invention also concerns a process to prepare a polymer having a melting point less than about 245.degree. C. which comprises contacting carbon monoxide and ethylene in the presence of one or more hydrocarbons C.sub.x H.sub.y containing an olefinically unsaturated --CH.dbd.CH-- group, where x is greater than 2 and less than 20, with a suitable catalyst and under conditions effective to prepare a linear random polymer having units of the formula --CO--(C.sub.2 H.sub.4)-- and units of the general formula --CO--(C.sub.x H.sub.y)--, and having a melting point less than about 245.degree.
