This article investigates the influence of the molecular weight of a copolymer, its chemical composition, and the concentration of the copolymer in mineral oil on thermal stability. The thermooxidative stability of copolymers was examined in a dynamic regime of heating from 20/sup 0/ to 500/sup 0/C at a rate of 5/sup 0/C/min. by means of thermal analysis. The breakdown rate constant was calculated at 200/sup 0/, 210/sup 0/ and 220/sup 0/C in order to investigate the effect of temperature on the rate and to calculate the activation energy. It is determined that as the molecular weight of the copolymer is increased from 11,000 to 17,000, the thermal stability decreases. Increasing the content of styrene in the copolymer composition improves its thermal stability.
