- 摘要： In the present work, blends of poly (phthalazinone ether sulfone ketone) (PPESK) /poly(tetrafluoroethylene) (PTFE) with various weight ratios were prepared by solution mixing. The dynamic mechanical properties including the storage modulus(E'), loss modulus(E") and loss tangent were studied over a wide range of temperature and frequencies and compared for PPESK and its blends. The results show that novel PPESK possesses high storage modulus within a high temperature range and shows good thermal stability. The peaks representing the loss modulus and tan 6 of blends shifted to higher temperatures with increasing scanning frequency. The glass transition temperature (T-g) of PPESK/PTFE was not enhanced when the content of PTFE in blends was more than 10wt %. The Arrhenius relationship has been used to calculate the activation energy of the glass transition of PPESK and its blends.
