Notizen:
A high-molecular-weight poly(leuco base) (Mn = 11000-18000) was obtained by addition polymerization of N,N′-dibenzyl-4,4′-methylenedianiline (2) and 2,2-bis[4-(2,3-epoxypropoxy)-phenyl]propane (diglycidyl ether of Bisphenol A) (1).The oxidation of this addition polymer with chloroanil, iodine, bromine, chlorine or antimony pentachloride results in polymeric dyes (absorption at λ = 620 nm) containing units of the “Michler Hydrolblau” type. The dielectric behavior in the frequency range 102 Hz up to 107 Hz shows a dependence of the conductivity on the temperature. Polymer 4c exhibits a conductivity of σ = 6 · 10-6 S/cm at 134,3°C and 106 Hz.
