Synthesis of phenolformaldehyde oliqomers, modified imidazolines based on natural petroleum acids and polyamines
Synthesis of phenolformaldehyde oligomers, modified imidazolines based on natural petroleum acids and polyamines were studied. As the amine compounds in the preparation of imidazolines diethylene triamine, triethylene tetramine, polyethylene polyamines were used. The component, and the mass composition of phenolformaldehyde oligomers, modified with different imidazolines, terms of their receipt were resulted. Significance of the research was grounded.
