Abstract
For the first time, there were offered consecutive stages of algorithm solution, such as phenolic antioxidants in the improvement of mechanical properties of polymers. The first step begins with studies of thermokinetic characteristics of thermolysis reactions of phenolic antioxidants accompanied by determination of their kinetic constants (activation energy, E and pre-exponents, Z). Modifiers of the main group of antioxidants can be distinguished according to the ratio of these constants. Polymer modification effect by them was determined at the second step. It appears in a temperature of the beginning of modifier decomposition under polymer thermal processing conditions. Furthermore, parameters of an increase in product service time under extreme operating conditions were defined. Examples are given of modification and stabilization of properties of polymer-derived composites
