Resumen:
Linear amphiphilic epoxy polymers synthesized by the polyaddition of diglycidyl ether of bisphenol A (DGEBA) with alkylamines like octylamine (OA), dodecylamine (DA) and hexadecylamine (HA), undergo a physical gelation process through tail-to-tail association of alkyl chains. SAXS spectra showed that tail-to-tail associations of alkyl chains were present since the beginning of polymerization and remained in the final materials.
