Description
The objective of this work was to evaluate the effects of high energy radiation on the mechanical and rheometric properties of butyl rubber compounds irradiated at doses of 5, 15, 25, 50, 100, 150 and 200 kGy. There was a marked decrease in the values of stress and elongation at break for doses higher than 50 kGy, showing changes in the polymeric chain due to chain scission and the formation of free radicals. The rheometric analysis showed that the maximum torque (MH) decreases as a function of increasing the dose, confirming the predominance of chain scission
