INFRARED SPECTRA OF IRRADIATED POLYETHYLENE
Journal Article

· J. Appl. Polymer Sci.
The irradiation of polyethylene caused a number of molecular rearrangements in the chemical structure of polyethylene. In addition to the significant changes in the type and distribution of unsaturated groups, an infrared comparison of the radiation induced chemical changes that occur in air and in a vacuum showed that the presence of oxygen has a marked influence on the structural rearrangements that occur on irradiation. The infrared spectra of irradiated single crystals prepared by two different means indicated the location of vinyl groups in the crystals and their protection from radiation by aromatic structures. From the data, a number of reaction mechanisms are postulated that can contribute to the understanding of irradiation effects on polyethylene. (auth)
