Abstract :
The authors show that high-energy electron irradiation of polyethersulphone brings about changes in the behaviour of both its steady-state and time-resolved fluorescence. This is due largely to the degree of crosslinking that takes place within the material, although it is recognised that chain scission also occurs to a certain extent. Thus, fluorescence is demonstrated to be a viable technique for monitoring structural changes in polymers
