The free-radical retrograde-precipitation polymerization (FRRPP)
process was introduced by the author in the early 1990s as a chain
polymerization method, whereby phase separation is occurring while
reactive sites are above the lower cr- ical solution temperature
(LCST). It was evident that certain regions of the product polymer
attain temperatures above the average ?uid temperature, sometimes
rea- ing carbonization temperatures. During the early stages of
polymerization-induced phase separation, nanoscale polymer domains
were also found to be persistent in the reacting system, in
apparent contradiction with results of microstructural coarsening
from constant-temperature modeling and experimental studies. This
mass con?- ment behavior was used for micropatterning, for
entrapment of reactive radical sites, and for the formation of
block copolymers that can be used as intermediates, surf- tants,
coatings, coupling agents, foams, and hydrogels. FRRPP-based
materials and its mechanism have also been proposed to be relevant
in energy and environmentally responsible applications. This
technology lacks intellectual appeal compared to others that have
been p- posed to produce polymers of exotic architectures. There
are no special chemical mediators needed. Control of conditions and
product distribution is done by p- cess means, based on a robust
and ?exible free-radical-based chemistry. Thus, it can readily be
implemented in the laboratory and in production scale.
