摘要：

The decomposable mandrel technique is an important method for fabrication inertial confinement fusion targets. The effects of three kinds of initiators including azobidsisobutyronitrile (AIBN), benzoyl peroxide (BPO) and di-tert-butyl peroxi de(DTBP) on the thermal degradation of poly(α-methylstyrene) (PAMS) were investigated by TG/DTG. The thermal pyrolysis products of PAMS were characterized by GC-MS. The experimental results show that the complete degradation temperature of PAMS is 339.8℃ with adding DTBP, and 50℃ less than that of PAMS without initiators. The thermal pyrolysis behaviour of PAMS is not affected by the DTBP content. To reduce uncertainty of target fabrication, the DTBP content is as little as possible. However, the complete degradation temperatures of PAMS with adding AIBN or BPO are 364.5℃ and 374.3℃, respectively, and there are macromolecules in the pyrolysis products of PAMS with AIBN, which could reduce degradation of PAMS and the quality of targets. ©, 2015, Chengdu University of Science and Technology.
