Prediction of Mechanical and Functional Features of Aged Rubber Composites Based on BR/SBR; Structure-Properties Correlation

In this study, the structure-properties relationship between the thermal factors of BR/SBR blends [normalize factor h BR 100 hBR 100 − hBR x, and the maximum peak temperature difference of thermal decomposition of BR and SBR Δ T max = T max BR − T max SBR ] with their aging time (1 to 40 days) was demonstrated using DTG profile of uncured compounds. The correlation between these two thermal factors with aging time yielded a linear equation with an acceptable correlation coefficient (R2 ≥ 0.95). By the obtained linear model the aging time of rubber compounds based on BR...
