      as an industrial byproduct of oil refining, furfural extract oil from reduced-pressure route ii with high aromatic content was used to prepare heat-resistant condensed polynuclear aromatic (copna) resin for the first time. the basic properties of furfural extract oil and the resultant copna resin were characterized by infrared spectroscopy (ft-ir), nuclear magnetic resonance spectroscopy (1h-nmr), thermogravimetric analysis (tga) and elemental analysis (ea). the result showed that heat treated furfural extract oil was successfully used for the synthesis of heat-resistant copna resin. the average structural parameters of raw materials and prepared resin were calculated by the improved brown-ladner method, and the averaged molecular structure of the resin was obtained. the reaction mechanism for the synthesis of copna resin was suggested as an acid-catalyzed positive ion type polymerization.
