The stability of benzotrifuroxan （BTF） and its mixtures with TATNB,TCTNB or NaN3 was studied The explosive performance of BTF was affected by all impurities.NaN3 could increase the thermal sensitivity of BTF,whereas TATNB could enhance the mechanic sensitivity.
Electronic spectroscopy of chemical analysis(ESCA)was used to study the surface composing of flu polymer F 2314 .The structure and composing of the copolymer was investigated according to each of the ClS spectra.Furthermore,the possible chain link mode was estimated.Comparing the spectra of undissolved part with F 2314 copolymer,there are some differences between the compose,but the chain link mode remains the same.The results of the experiment indicated that the increase of the proportion of CTFE in undissolved sample affected the solubility of F 2314 copolymer in different batches.
