Abstract: The temperature dependence of resistance to crack extension and tearing modulusof phenolphthalein polyether ketone(PEK-C)has been investigated.The relationship between tearing instability of PEK-C and temperature has been discussed.

Key words: phenolphthalein polyether ketone, tearing instability, ductile fracture
