Experimental methods for estimation of stabilizers efficiency

Experimental methods for estimation of efficiency of stabilizers of various classes as phenols, amines, phosphites etc. in various model systems both on the base of polymer and without polymer (lowmolecular) are described. The large experimental material considered is obtained with the help of various physicochemical methods: manometry, spectroscopy, DTA, calorimetry, chemiluminescence, viscosimetry, polarography etc. The determination of the regularities in the changes of efficiency of stabilizers with various structures and reactivities allows to choose the most perspective ones for practical use and to step up to looking for new active stabilizers more reasonably and purposefully. The elaboration of a mathematical model of the oxidation process permits to create the base for semi-empirical forecast of the stabilizers properties.
