摘要：

The efficiency and the action mechanism of trivalent phosphorus compounds have been investigated as inhibitors of the autoxidation of a polyether alcohol in relation to the structure of the phosphorous components. The induction periods of autoxidation, the critical antioxidant concentrations and the rate of decomposition of polyether alcohol hydroperoxides by different phosphorous antioxidants have been determined by oxygen uptake measurements and by following the hydroperoxide and carbonyl group formation. The transformation products of phosphorous compounds have been studied by P-31-NMR spectroscopy and their influence on the autoxidation of the polyether alcohol has been investigated.
