subject because these methods can provide branched polymers with backbones
that are also well-defined in terms of the length, the composition, and their distribution.
Characterization of the poly(macromonomers) prepared by homopolymerization
has proved that they provide a useful probe for discussing the structural
characteristics of the star and brush polymers. Graft copolymers have been and
will be a most important area of application of the macromonomer technique
since a variety of multi-phased and microphase-separated systems can easily be
designed just by an appropriate combination of a macromonomer and a conventional
monomer. In general, however, characterization of their absolute MW,
branch/backbone composition as well as their distributions remain to be studied
in more detail.
Amphiphilic macromonomers work effectively as reactive (copolymerizable)
emulsifiers and dispersants for heterogeneous polymerizations. They are successfully
applied to the design of the polymeric microspheres of submicron to
micron size. Introduction of additional functions, such as environment-sensitivity,
will be a matter of interest in the potential application of the macromonomer
technique.
