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 etermined. Stabilizing system efficiency was estimated on the asis of induction time values (t(i)) of PE-LD oxidation rocess at temp. 210degreesC and 220degreesC. Induction time alues have been determined from DTA measurements. On the basis f interaction coefficient (Theta) values calculated from quation (1) it has been found that the components of chosen tabilizing system show interaction synergism (Theta > 1) which ignificantly depends on molar ratio of the components. The ptimal ratio is equal to 0.5.
