of from about 90 1 to about 1 1 and still more preferably from about 95 1 to about 1 1 in another embodiment the invention provides a polymerization method for reacting an olefin feed and a synthesis gas feed under free radical copolymerization conditions to produce the olefin co copolymer composition described above the free radical polymerization process uses organic peroxides as a free radical initiator according to conventional methods well known to those skilled in the art representative initiators include but are not limited to dialkyl peroxides such as ditertiary butyl peroxide 2 5 dimethyl 2 5 ditertiary butyl peroxyhexane di cumyl peroxide alkyl peroxides such as tertiary butyl hydroperoxide tertiary octyl hydroperoxide cumene hydroperoxide aroyl peroxides such as benzoyl peroxide peroxy esters such as tertiary butyl peroxypivalate tertiary butyl perbenzoate and compounds such as azo bis isobutyronitrile free radical initiators with an appropriate half life at reaction temperatures ranging from about 50 u00b0 c to about 230 u00b0 c can be used of these t butyl peroxypivalate which has a half life of about 10 hours at 66 u00b0 c is preferred typically copolymerization will occur at temperatures ranging from about 50 to about 230 u00b0 c and preferably from about 50 u00b0 c to about 200 u00b0 c pressures can range from about 100 to about 30 000 psig and preferably from about 100 psig to about 3 000 psig of course the copolymerization is accomplished in the presence of a free radical initiator having an appropriate half life preferably the reaction occurs in the presence of a solvent suitable solvents include toluene benzene dioxane pentane heptane hexane propylene oxide cyclohexane supercritical carbon dioxide and the.
