ABSTRACT The preparation of graft copolymers utilizing monomers of diverse physical characteristics is extremely difficult. The present invention seeks to overcome this drawback by providing a process for preparing a copoly- merizable macromolecular monomer comprising preparing a living polymer by polymerizing at least one anionically polymerizable monomer in the presence of an anionic polymerization initiator to thereby form a monofunctional living polymer with a narrow molecular weight distribution, and thereafter reacting the monofunctional living polymer with a halogen-containing epoxide or halogen-containing vinyl compound selected from the group consisting of acrylyl chloride, methacrylyl chloride, vinyl haloalkyl ethers, vinyl esters of haloalkanoic acids, allyl halides, methallyl halides, vinyl halides, halomaleic anhydrides, halomaleate esters, and epihalohydrins.
