Abstract: Astudy has been made for the crystallization behaviour of poly(ether ether ketone ketone) by DSC which was used to monitor the crystallization process from the melt and rubbery state.The Avrami equation was used to analyze the isothermal crystallization kinetics of PEEKK.The Avrami constant n is about 2 for the crystallization process from the melt and 1.5 from the rubbery state.The activation energies for PEEKK are 953.7 kJ/mol for crystallization from the melt and 932.6kJ/mol for crystallization from the rubbery state.The kinetic parameter kgis 851.5K

Key words: Poly(ether ether ketone ketone), Isothermal crystallization kinetics, Differential scanning calorimeter
