By the amination of a fraction of n-polychloroparaffins (C13-19) with 1,2-ethylenediamine in a basic medium, oligopolyamines were obtained. The obtained products were characterized with spectroscopic, titrimetric, and elemental analyses and tested as adhesives for road bitumens. The samples, containing over 7.0% bound nitrogen in a concentration of 1.0 mass % with respect to the bitumen mixtures, were characterized by maximum effectiveness, that is, 1.00% adhesion between the bitumen and the mineral fillers.
