Abstract: Four methods of modification of tung oil are introduced，and the progress of modification of tung oil and its derivatives in the application of polymer materials is reviewed. The modification mechanisms of tung oil by Diels-Alder reaction，Friedel-Crafts reaction，oxidative polymerization and free radical polymerization are discussed. On this basis，the prospect of modification of tung oil and its derivatives in the application of polymer materials is also presented．
