摘要：
The thermal decomposition behaviors of GAP based energetic thermoplastic polyurethane used in solid propellant were studied on the basis of TG and DSC analysis, and the activation energy Ea and the pre-exponential factor lnA were calculated by using Kissinger and Ozawa method. The results of TG indicate that the thermal decomposition process of ETPUE comprises three stages: azide groups, hard segments, and soft segments decomposition, respectively. The decomposition mechanism function of the first stage, as well as the effects of hard segment content on the decomposition behaviors of ETPUE were investigated in detail.
