概要	Cardanol novolac (CDN) was synthesized by the reaction of cardanol (CD) and paraformaldehyde in the presence of oxalic acid. The prepolymerized compounds of CD/4,4'-bismaleimidodiphenylmethane (BMI) and CDN/BMI with cardanol/maleimide unit ratios 1/2, 1/4 and 1/6 at 200 degree C were compression-molded at finally 250 degree C for 5 h to produce cured CD/BMI (cCD/BMI) and cured CDN/BMI (cCDN/BMI) resins. Although the 1H NMR and FT-IR analyses of the model reaction product of CD and N-phenylmaleimide (PMI) at 200 degree C for 8 h suggested the occurrence of the ene reaction and subsequent Diels-Alder reaction, the FT-IR analysis of cCD/BMI and cCDN/BMI suggested the occurrence of the ene reaction and addition copolymerization. The cCD/BMI and cCDN/BMI with ardanol/maleimide ratio lower than 1/2 did not show glass transition until 300 degree C and had 5% weight loss temperature higher than 450 degree C.
