Abstract
The thermal properties of monoalkyl(C8-C12)phenol-formaldehyde oligomers modified with imidazolines synthesized from fatty acids of vegetable oils and polyamines (diethylenetriamine, triethylenetetraamine, and polyethylenepolyamines) at different molar ratios have been studied. Fatty acids are obtained by saponification of sunflower and corn oils, followed by the interaction of a mixture of their salts with hydrochloric acid. The dependence of thermal characteristics on the composition of oligomers was studied, regularities were revealed in comparison with unmodified analogues. Appropriate conclusions are drawn.
