A graft block copolymer is comprised of a completely saturated olefinic backbone with pendant anionic polymer side chains. The polymer is produced by copolymerizing an .alpha.-olefin with a monomer which contains a functional group which can be metallated so an anionic monomer can be polymerized therefrom, metallating the copolymer by reaction with metal alkyl or aryl compound and a metallation activator, and growing anionic polymer side chains from the copolymer backbone by reacting an anionically polymerized monomer with the metallated copolymer.
