A new benzoxazine with two perfluorohexyl side chains (M1) was synthesized and its homopolymerization was investigated. The results showed that the curing of M1 was occurred at near 257 ℃, whereas the curing onset temperature can be lowered to 183 ℃ when a catalyst of 5 wt% imidazole was added. The cured M1 exhibited higher thermal stability with 5% and 10% weight loss temperatures of 337 and 382 ℃, and a char yield of 45.9%, respectively. The cured M1 exhibited also good electrical properties with dielectric constant of 3.78 in a frequency of 1 MHz. The water absorption of the cured M1 was below 1%, and the surface free energy was 6.98 mN/m, respectively.
