Notes:
Infrared absorption spectroscopy has been used to demonstrate dose rate dependence of trans-vinylene unsaturation in irradiated Marlex 50 polyethylene. When the irradiated polymer is stored in vacuum a decrease is observed in trans-vinylene absorbance over a period of several weeks. After high dose rate irradiation the decay is preceded by an initial increase. These phenomena are ascribed to the reaction of “trapped” radicals.
