The Synthesis of Nitrogen-Containing Phenol Formaldehyde Oligomers Grafted with Vegetable Oils

Abstract

The synthesis of nitrogen-containing alkyl(C8–C12)phenol formaldehyde oligomers grafted with vegetable oils was investigated with the aim of creating new materials with the properties of protective coatings. Soybean and linseed oils were used as the vegetable oils. The interaction between phenol formaldehyde oligomers and vegetable oils probably occurs through the functional groups formed as a result of oxidative processes at the carbon atoms in the a-position to double bonds. The probable structure was established using infrared and nuclear magnetic resonance spectroscopy, and the physicochemical properties of the synthesised products were studied.
