| Abstract: | In this paper,the isothermal and nonisothermal melt crystallization kinetics of poly(aryl ether ether ketone diphenyl ketone)(PEEKDK) were studied by DSC.The isothermal crystallization behavior was analysed with avrami equation.The crystallization acrivation energy was 942kJ/mol.The equilibrium melting point T 0 m was estimated to be 445℃ by using Hoffman-Weeks approach.The nucleation rale parameter k g was also determined by Lauritzen_Hoffman equation and compared with those of PEEK and PEEKK.At the same time,the nonisothermal crystallization kinetic was also investigated by the Avrami equation modified by Jeziorny. |
