The invention is a linear random terpolymer comprised of repeating units of --CO--(C.sub.2 H.sub.4)-- and units of --CO--(C.sub.x H.sub.y)-- where x is greater than 2 and less than 20, having a melting point between about 150.degree. 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. C.
A linear polymer consisting essentially of an average of n units with the formula --CO--(C.sub.2 H.sub.4)-- and an average of m units with the general formula --CO--(C.sub.x H.sub.y)-- wherein the units are randomly distributed in the polymer, the quotient m/n is between about 0.33 and about 0.007, x is greater than 2 and less than 20, y is 2x, and the polymer has a melting point between about 150.degree. C. and 245.degree. C.
A linear polymer consisting of an average of n repeating units of the formula --CO--(C.sub.2 H.sub.4)-- and an average of m repeating units of the formula --CO--(C.sub.3 H.sub.6)--, wherein the units are randomly distributed in the polymer, said polymer having an m/n quotient between about 0.33 and about 0.023, and said polymer having a melting point between about 150.degree. C. and 245.degree. C.
An article of manufacture comprising a linear polymer consisting essentially of an average of n units with the formula --CO--(C.sub.2 H.sub.4)-- and an average of m units with the general formula --CO--(C.sub.x H.sub.y)-- wherein the units are randomly distributed in the polymer, the quotient m/n is between about 0.33 and about 0.007, x is greater than 2 and less than 20, y is 2x, and the polymer has a melting point between about 150.degree. C. and 245.degree. C.
