Abstract

Dielectric relaxation spectroscopy (DRS) and dynamic mechanical thermal analysis (DMTA) were used to investigate the secondary relaxation behaviour of poly(ether ether ketone) (PEEK), poly(etherimide) (PEI) and a miscible PEEK/PEI blend. The data from each technique, for the γ‐process, did not lie on the same Arrhenius line, while the rate of molecular motion of the γ‐process in the blends was largely an average of each component's motions. The β‐process in PEI was plasticised by the presence of PEEK.

The mechanical and dielectric relaxation of a set of aromatic-aliphatic polyamides containing ether linkages have been examined as a function of temperature (0140 to 190ЊC) and frequency (3 to 10 6 Hz). The polymers differ in the orientation (meta and para) of the aromatic rings, in the length of th
