摘      要：Three new borazine derivatives,2,4,6-tri（allylamino）borazine （CH 2 =CHCH 2 NHBNH） 3 （1）,2,4,6-tri（3ethynylanilino）borazine （CH≡CC 6 H 4 NHBNH） 3 （2）,and 2,4,6-tri（4-propargyl oxyanilino）borazine （CH≡ CCH 2 OC 6 H 4 NHBNH） 3 （3） were synthesized by reaction of 2,4,6-trichloro-borazine Cl 3 B 3 N 3 H 3 （TCB） with corresponding primary amines,*** thermal behavior was studied by differential scanning calorimetry （DSC） and thermogravimetric analysis （TGA）.These molecules were easily crosslinked via thermal polymerization of reactive ethynyl or vinyl *** pyrolytic residues of borazines were investigated by X-ray photoelectron spectroscopy （XPS）,powder X-ray diffraction （XRD）,and scanning electron microscopy （SEM）.The analytic results indicated that B-C-N ceramics were formed upon pyrolysis of the borazines under an inert atmosphere.
