ABSTRACT

The macromolecular engineering of complex molecular
architectures through the introduction of controlled
branching or block copolymerization has continued to
assume an increasingly important theme in polymer science.
We have used a combination of different polymerization
techniques to prepare branched polymers with narrow
polydispersities and controlled molecular weights and
end-groups. Further elaboration has been demonstrated
through the use of libraries of new multifunctional
orthogonal initiators and functional dendrons together
with controlled polymerization processes. For example,
dendrimer-like star polymers are a new class of
macromolecules that allow the preparation of radial
block copolymers as well as the preparation of
topological isomers(1,2). The prepared isomers permitted
a unique opportunity to study physical and chemical
properties as a function of the molecular structure
for polymers with molecular weights of around 70,000
g/mol. Moreover, by varying the size of the dendrimer-
like star polymers they have been used to understand
differences and similarities between dendrimers and
star polymers. In the case of the dendrimer-like star
block copolymers the molecular architecture was shown
to have a pronounced affect of the morphology and
interfacial activity. These new polymers have been used
as macromolecular templates for the generation of
nanoporous low dielectric constant materials.(3)
