摘    要: 在聚-4-甲基-1-戊烯(pmp)低密度泡沫的制备中,利用示差扫描量热(DSC)分析仪对pmp聚合物在均四甲苯/萘所组成的溶剂/非溶剂二元体系中的凝胶化过程进行在线测量。测定了它的凝胶化范围以及凝胶化温度与冷却速率和pmp在溶剂/非溶剂体系中所占比例的关系。利用热重-示差扫描量热(TG-DSC)系统对所制备的低密度pmp泡沫的热性能进行了分析,得到了泡沫密度变化对热稳定性等的影响。

关 键 词:热重-示差扫描量热(TG-DSC)分析  低密度聚-4-甲基-1-戊烯(pmp)泡沫  ICF靶材料

Abstract:Preparation of low-density poly (4-methyl-1-pentene) foam (pmp foam) is described. The thermal analysis method is utilized to measure on line the gelation of pmp polymer in the binary solvent/nonsolvent (durene/naphthalene) system. The range of gelation temperature is preliminarily determined. The influence of mixture system composition and the cooling rate during the making of foams is discussed. TG-DSC is applied to determine the thermal properties of low-density pmp foams. And the effect of density’s change on the thermal stability of foams has been studied. These thermal analysis data play a great role in improving the foam quality.
Keywords:Gelation  Low-density pmp foam  material of ICF targets
