ABSTRACT:
A graft block copolymer is comprised of a saturated olefinic backbone with pendent anionic polymer side chains. The polymer is produced by copolymerizing an .alpha.--olefin with a 1-alkenyl monomer containing a functional group to which an anionically polymerized polymer can be grafted to produce graft block copolymer, anionically polymerizing at least one anionically polymerizable monomer to form living polymer chains, and then grafting the living polymer chains onto the copolymer to form the graft block copolymer.
