A branched polyolefin, preferably a polyethylene, and containing branches with even and odd numbers of carbon atoms, may be made by oligomerizing ethylene to an alpha -olefin using a selected iron containing catalyst, and then copolymerizing that alpha -olefin with ethylene and one or more other added alpha -olefins which have odd numbers of carbon atoms. The polymers are useful, for example, as molding resins. |
