摘要: 酞侧基聚芳醚酮(PEK-C)具有较高的玻璃化转变温度,其流变加工性能和力学性能已被广泛研究,被证明是一种很有前途的耐高温热塑性树脂,但聚合物能否应用于实际中,很大程度上也取决于其热学性能塑料制品的尺寸稳定性、柔韧性、使用期限等物理化学性能都具有温度依赖性,其热学行为在工程设计和加工成型及计算机模拟中都十分重要.本文研究PEK-C的pvT行为以及导热系数和比热容的温度依赖性.

Abstract: The pvT behavior and temperature dependence of thermal conductivity and specific heat of phenolphthalein poly(ether ketone)(PEK-C) at constant pressure were investigated.The Spencer-Gilmore equation of PEK-C was estimated.The glass transition temperature rises as the pressure goes up,and at higher pressure an obvious glass transition zone exists in pvT curves.The temperature dependence of thermal conductivity and specific heat is slight.

Key words: phenolphthalein poly(ether ketone), pvT behavior, thermal conductivity, specific heat
