Notes:
The kinetics of desorption for water from various ethylene polymers have been studied by weight loss. In either branched (DYNK) or linear (Marlex 50) polymers the solubility of water was too low to be measured by our techniques (〈 0.05 mg. H2O/g. polymer). This result is not in agreement with values reported by earlier workers (0.2-0.9 mg. H2O/g. polymer). When DYNK is oxidized, however, measurable quantities are absorbed. We find 0.11 mg. H2O/g. polymer for DYNK containing about 0.6% oxygen by weight. In this case the desorption data provide a measure of the diffusion coefficient, D ≃ 10-7 cm.2/sec. Similar results are found for a cable compound containing about 5% butyl rubber and 0.07% antioxidant introduced into DYNK by milling.
