Abstract
Novel, linear alternating polymer compositions of carbon monoxide and at least one ethylenically unsaturated hydrocarbon having a relatively wide molecular weight range are produced by contacting ethylene and unsaturated hydrocarbon in the presence of a polymerization catalyst under different polymerization conditions of temperature and pressure. One set of polymerization conditions will have a higher reaction temperature and a lower reaction pressure than another.
