Syntheses and characterization of branched polymers prepared by homo- and copolymerization
of macromonomers are reviewed. A number of macromonomers have so far been
available as potential building blocks to design a variety of well-defined, branched homoand
copolymers including comb, star, brush, and graft types. Recent progress in macromonomer
syntheses, macromonomers' homo- and copolymerization, characterization of the
branched polymers obtained, as well as application to design of polymeric microspheres
are described. Macromonomers and their homo- and copolymerization appear to provide
continuing interest in designing and characterizing a variety of branched polymers and in
their unique applications.
Keywords. Poly(macromonomers), Graft copolymers, Comb, Star, Brush, Polymeric microspheres
