B. Mattson et al., NOVEL TECHNIQUES USED TO ASSESS THE AGING OF CARBON-BLACK-FILLED MATERIALS, Polymer degradation and stability, 41(2), 1993, pp. 211-221
Four recently developed, sensitive techniques (density profiling, comp
uted X-ray tomography, modulus profiling and chemiluminescence) have b
een used to follow the thermooxidative ageing behavior of a carbon-bla
ck-filled EPDM terpolymer. Comparisons between the results obtained fr
om the four techniques indicate the existence of a complex ageing beha
vior dominated by diffusion-limited oxidation effects.
