Abstract

Surface tension of kraft lignin (KL) and KL/poly(N,N-dimethylaminoethyl methacrylate) mixtures, with different composition at the air-water interface depending on pH and temperature, was measured. It was found that the surface activity of both KL and the reaction mixtures grows with decreasing pH and increasing temperature. At the same time, the surface activity of the KL/poly(N,N-dimethylaminoethyl methacrylate) reaction mixture, irrespective of its composition under the same environment conditions, considerably exceeds the surface activity of KL, indicating the synergetic effect governed by the peculiarities of the polymeric structure of the formed soluble particles of the polyelectrolyte complex.

Keywords: kraft lignin; polyelectrolyte complex; surface tension; synergetic effect
