Аннотация: For the first time water soluble copper-containing polymers based on sulfated ethanol lignin of abies wood were obtained by the method of ion exchange. Their composition and structure were studied with the use of elemental and chemical analysis, infrared spectroscopy (IR), atomic absorption, electron paramagnetic resonance (EPR). TПоказать полностьюhe absence of nitrogen for copper cations in the resulting polymer indicates the complete substitution of ammonium cations in the ammonium salt of sulfated ethanol lignin. In EPR spectrum of copper-containing sulfated ethanol lignin there is a superposition of two signals. One of them belongs to isolated Cu2+ ions, the other to exchange-bound Cu2+ ions in salt-like compounds. The integral intensity of signal of isolated Cu2+ ions (anisotropic signal) and exchange-bound ions (isotropic signal) depends on the copper content in the polymer.
