Abstract. Self-assembly of hyperbranched polyethylenimine (PEI) and fatty acids leads to supramolecular inverted micellar structures that are able to irreversibly transfer water-soluble guest molecules into organic solvents.Perez Prieto, Julia, Julia.Perez@uv.es ; Stiriba, Salah Eddine, Salah.Stiriba@uv. The results obtained by in situ monitoring the polymerization using NMR and MS indicated that hyperbranched poly(TMPTA1-AEPZ2) was formed via a A(B'B'')2 intermediate, and the B' ' (the formed 2 degrees amine) was kept intact in the reaction. Therefore, poly(TMPTA1-AEPZ2) contained secondary and tertiary amines in the core and primary amines in the periphery similar to polyethylenimine (PEI). The chemistry of protonated poly(TMPTA1-AEPZ2) was further confirmed by 13C NMR, and the molecular.
