Abstract
Using the methods of differential scanning calorimetry, volumetry, and IR absorption spectroscopy a comparative study was carried out of the influence of the addition of mono- and dihydric sterically hindered p henols on the relaxational transitions, melting and thermooxidation of polyethylene and a radiation-crosslinked polyethylene, irradiated to total doses of 5.0.10(4)-1.0.10(6) Gy. It was shown that 3,5-ditert-bu tylpyrocatechol in a 0.5-1.0% by weight content is the most effective thermostabilizer for the radiation crosslinked polyethylene.
