摘要：

The results of investigations of PE-LD stabilization with two-component system consisting of commercial stabilizers: "Irganox 1010" and "Ultranox 626" are presented. The effect of molar ratio of components on the system efficiency has been determined. Stabilizing system efficiency was estimated on the basis of induction time values (t(i)) of PE-LD oxidation process at temp. 210degreesC and 220degreesC. Induction time values have been determined from DTA measurements. On the basis of interaction coefficient (Theta) values calculated from equation (1) it has been found that the components of chosen stabilizing system show interaction synergism (Theta > 1) which significantly depends on molar ratio of the components. The optimal ratio is equal to 0.5.
