A REVIEW OF OXYGEN-UPTAKE TECHNIQUES FOR MEASURING POLYOLEFIN OXIDATION

The application of oxygen uptake techniques to the determination of po lyolefin stability is extensively reviewed and includes the considerat ion of both manometric apparatuses and devices which incorporate press ure transducers. The sensitivity of oxygen uptake instruments, types o f heating facilities, molecular sieves and absorbents, the shape of th e oxygen uptake profile and the technique of oxygen uptake as related to other techniques are also discussed. A comprehensive table listing oxygen uptake apparatuses in chronological order is included in the re view.
