Resumen:
In a recent paper (Zucchi, I. A.; et al. Macromolecules 2008, 41, 4895), we showed that linear
amphiphilic epoxy polymers synthesized by the polyaddition of diglycidyl ether of bisphenol A (DGEBA)
with dodecylamine (DA) could undergo a physical gelation process through tail-to-tail association of dodecyl
chains. The aim of the present study was to analyze in more detail conditions leading to the formation of
epoxy networks with physical cross-links by the reaction of DGEBA with alkylamines of different chain
lengths: octylamine (OA), dodecylamine (DA), and hexadecylamine (HA). SAXS spectra showed that tail-totail
associations of alkyl chains were present since the beginning of polymerization and remained in the final
materials. Initially, these associations correspond to micelles of the alkylamines dispersed in the solvent
(DGEBA). In the course of polymerization, micelles are disaggregated as the individual alkylamine chains
become part of the linear amphiphilic polymer. However, tail-to-tail associations among alkyl chains
attached to the polymer backbone persisted in the final materials. Reactions were followed by rheometry
at 100 C. For every system, a significant discontinuity in the increase in the storage modulus observed at
advanced conversions was assigned to a phase inversion process produced by solvent depletion. By annealing
prolonged times at the reaction temperature, a crossover of storage and loss modulus was observed because of
the increase in the extent of associations among alkyl chains leading to a physical gel. Times for physical
gelation varied in the order OA < DA < HA. Both DGEBA-DA and DGEBA-HA polymers could be
reversibly transformed from gel to liquid states by appropriate heating-cooling cycles; however, the
DGEBA-OA polymer showed no thermoreversibility. Physical gels exhibited a high swelling capacity in
THF (HA > DA > OA). These amphiphilic gels could be used as dispersion media for a variety of
nanoparticles stabilized with alkyl chains. They can also be the basis of single-component thermally
remendable epoxy networks.
