An analytical method to evaluate quantitatively the material changes due to oven-aging, oil migration and aging under dynamic conditions is introduced. The method uses the power law relation, λb M100-0.75, which holds for the material change due to crosslinking as the reference change.

Keywords: Aging, Oil Migration, Dynamic Condition, Crosslinking, Scission, Extension Rate at Break, 100% Modulus
