V. Capodanno et al., EFFECT OF PHYSICAL AGING ON THE PROPERTIES OF FILMS OF AMORPHOUS POLY(ETHER ETHER KETONE) (PEEK), Journal of applied polymer science, 65(13), 1997, pp. 2635-2641
Physical aging of films of poly(ether ether ketone) kept for 2 months
at 120 degrees C was studied. The extent of aging was evaluated with d
ifferent techniques. Aged samples show different thermal behavior and
exhibit different mechanical, transport, and viscoelastic properties.
An attempt was made to establish the accuracy of different techniques
and their reliability in detecting the extent of physical aging. (C) 1
