The role of strain rate (\(\dot \varepsilon\)) in strain induced crystallization (SIC) of vulcanized natural rubber (NR) and synthetic isoprene rubber (IR) was studied by in-situ wide angle X-ray scattering (WAXS). The nucleation rate (I) was determined by measuring the slope on the plot of the scattering intensity (IX) as a function of time (t). Various I values were determined for various \(\dot \varepsilon\). On the plot of I vs. \(\dot \varepsilon\), we found that I is proportional to \(\dot \varepsilon\); I ∝ \(\dot \varepsilon\)
