Abstract
Time domain dielectric methods have been used to compare the dynamics of the cu relaxation of poly(aryl ether ketone) polymers. The real tim e variation of the macroscopic dielectric decay functions with crystal lization time has been interpreted assuming an increase in the intermo lecular cooperativity of the ct relaxation as the polymer chains are o bliged to move between crystalline regions.
