Description	The thermal characteristics and decompn. kinetics of C4-bonded PBXs based on some attractive cyclic nitramines were investigated by means of nonisothermal TG and DSC techniques. It is shown that only a single decompn. process is obsd. for RDX-C4 while an obvious two-step process for mixt. of BCHMX-C4, CL-20-C4, and HMX-C4. The onset temp. of the exotherms were obsd. at 216.3, 238.7, 279.2, and 236.7° with the peak temps. of 235.1, 279.0, 231.2, and 233.7° for RDX-C4, BCHMX-C4, HMX-C4 and CL-20-C4, resp. Their corresponding exothermic decompn. processes were covered by energy changes of 1749, 1938, 1213, and 2639 J g-1, which are lower than that of their pure cyclic nitramines. It was also proved that C4 matrix has significant effect on the activation energy distribution of RDX, BCHMX and CL-20, whose initial autocatalysis effect was inhibited or weakened. With regard to HMX-C4, the activation energy of its initial step is much lower than that of the second step.
