A commercial poly(ether sulfone) has been examined by electronic spectroscopy, continuous photolysis, and laser flash techniques. The spectroscopic experiments indicate that the chromophoric species primarily responsible for light absorption in the region 290–350 nm is the diphenyl sulfone unit. The laser flash experiments give direct evidence of bond scission at the ether linkage on the polymer backbone.
