| 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。

| 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 (durene/naphthalene) or nonsolvent system. The range of gelation temperature is preliminarily determined. The influence of mixture system composition and the cooling rate during the process of making foams is discussed. TG DSC is applied to determine the thermal properties of low density pmp foams. And the effect of density change on the thermal stability of foams has been studied. These thermal analysis data play a great role in improving the foam quality. |
