Thermal Properties of Phenolphthalein Poly(Ether Ketone)

酞侧基聚芳醚酮的热学性能谢红卫，李滨耀（中国科学院长春应用化学研究所长春１３００２２）关键词酞侧基聚芳醚酮，ｐｖＴ行为，导热系数，定压比热容酞侧基聚芳醚酮（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［１～３］，被证明是...

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.
