Abstract
The absorption/emission spectra and kinetics of excited states (single ts and triplets) and ions generated by pulse radiolysis method in the polyethylene-solute (dimethyldiphenyl, pyrene) systems were investigat ed. It was found that excited states of aromatic admixtures were forme d as a result of ion recombination in micro/millisecond time scales at temperatures higher than T-g. Solute excimer emission was observed fr om pulse-irradiated PE samples at room temperature. The mechanism of e xcimer formation was discussed.
