含DOPO的双酚A-单苯并嗪合成、表征及其固化特性
Synthesis, characterization and curing characteristics of single benzoxazine containing DOPO based on bisphenol A
摘要
Abstract
Double benzoxazine based on bisphenol A(DBOZ)was synthesized from bisphenol A, aniline and paraformaldehyde, and the single benzoxazine containing DOPO based on bisphenol A(DBDO)was synthesized from DBOZ and DOPO. FT-IR, NMR (1H NMR and 13CNMR) were used to characterize the chemical structure of DBOZ and DBDO. Curing characteristics were studied with DSC and thermostability was studied with TG. In N2 atmosphere, the ring opening polymerization of DBOZ took place at about 205℃, and initial decomposition temperature was 312℃. At 373℃, the fastest decomposition was achieved. At 800℃, carbon residue was 37.19%. In N2 atmosphere, initial decomposition temperature of DBDO was 353℃. At 443℃, the fastest decomposition was achieved. At 800℃, carbon residue was 39.60%.关键词
