The bisphenol A contained double DOPO (2DO) was synthesized by using double benzoxazine based on bisphenol A(DBOZ) and DOPO. And the double benzoxazine contained double DOPO based on bisphenol A (2DD) was synthesized by using 2DO
aniline and paraformaldehyde. FT-IR
NMR were used to characterize the chemical structure of 2DO and 2DD. Curing characteristics were studied with DSC and thermostability was studied with TG. In N2 atmosphere
initial decomposition temperature of 2DD was 353℃. At the temperature of 442℃
the fastest speed of decomposition was achieved. At the temperature of 800℃
carbon residue was 40.40%. Mass-change rate at the temperature of 300℃ was 3.97%. Compared with double benzoxazine based on bisphenol A
initial decomposition temperature increased by nearly 41℃
the fastest speed of decomposition increased by nearly 70℃ and carbon residue increased by nearly 3.21%.
