New Efficient Dielectric and Antistatic Materials Based on Oligoaminophenols

Abstract

New polyconjugated oligomers—oligoaminophenols—have been prepared by the oxidative polycondensation reaction of aminophenols (APs) in the presence of oxidants (H2O2, NaOCl, KOH plus O2). It has been established that the reactivity of AP increases with the series of m- < o- < p-isomers in this reaction. The oligoaminophenols synthesized show a high reactivity in electron-exchange processes and in reactions with the oxirane ring of epichlorohydrin and epoxy resins. They are highly efficient antioxidants and antistatic agents. © 1997 SCI
