Abstract
A polymer of an alpha-olefin and at least one diene with low residual unsaturation and long chain branching and the process for preparing said polymer. The process comprises polymerizing an alpha-olefin (ethylene) with at least one diene in the presence of a coordination catalyst, the diene being selected from linear .alpha.,.omega.-dienes of at least eight carbon atoms (1,7-octadiene) and cyclic endomethylenic dienes (bicyclo(2,2,1)-2-5-heptadiene, dinorbornene), the diene being characterized in that each one of the two double bonds is readily polymerizable.
