| Abstract: | Although hydrogen gas is about tenfold more soluble in hot-filtered mats of polyethylene (PE) single crystals (SC) than in bulk linear PE, we found that no hydrogen solubility at all could be measured in freeze-dried SC. Despite this, hydrogen gas still exerts a catalytic effect on alkyl radical decay on both the fast and slow first-order decay reactions in the freeze-dried samples. Above 40°C the first-order decay constants of the slowly decaying component decrease with increasing fold period. |
