| 概要 | 5,5'-Bieugenol (BEG) and eugenol novolac (EGN) were synthesized by the oxidative coupling reaction of eugenol (EG) and the addition-condensation reaction of EG with formaldehyde, respectively. The EG, BEG and EGN were prepolymerized with 4,4'-bismaleimido-diphenylmethane (BMI) at 180 degree C and then compression-molded at finally 250 degree C for 6 h to produce cured EG/BMI (EB), BEG/BMI (BB) and EGN/BMI (NB) resins with eugenol/maleimide unit ratios of 1/1, 1/2 and 1/3. The 1H and 13C NMR analyses of the model reactions of EG, BEG and EGN with N-phenylmaleimide (PMI) at 200 degree C for 12 h revealed that the ene reaction and subsequent Diels-Alder/ene reactions mainly occurred for EG/PMI, while thermal addition copolymerization mainly occurred for BEG/PMI and EGN/PMI. The glass transition temperature (Tg) and 5% weight loss temperature (T5) of the cured resin increased with increasing BMI content, and EB 1/3 showed the highest Tg 377 degree C and T5 475 degree C. |
