概要 | The reaction of tung oil (TO) and 1,1'-(methylenedi-4,1-phenylene)bismaleimide (BMI) in DMI at 150 degree C and subsequent precipitation gave TO/BMI prepolymer, which was cured at 200 degree C gave crosslinked TO/BMI product. The FE-SEM analysis revealed that all the cured products are homogeneous and no phase separation was observed. The glass transition temperature and 5% weight loss temperature of the cured TO/BMI increased with increasing BMI content. The maximal tensile strength and modulus were obtained for the cured products with the C=C ratios of 1/2 and 1/3, respectively. The model reaction products of TO and N-phenylmaleimide (PMI) in DMI were analyzed by 1H-NMR spectroscopy. The NMR data of the reaction products of TO/PMI at 150 degree C for 24 h revealed that Diels-Alder reaction preferentially occurred at 2/1, and that ene reaction and other reactions such as radical homo- and co-polymerization gradually increased with decreasing C=C ratio of TO/PMI. |
