Abstract
Dielectric relaxation spectroscopy (DRS) and dynamic mechanical therma l analysis (DMTA) were used to investigate the secondary relaxation be haviour of poly(ether ether ketone) (PEEK), poly(etherimide) (PEI) and a miscible PEEK/PEI blend. The data from each technique, for the gamm a-process, did not lie on the same Arrhenius line, while the rate of m olecular motion of the gamma-process in the blends was Largely an aver age of each component's motions. The beta-process in PEI was plasticis ed by the presence of PEEK.
