The diffusion of some aromatic solvents (benzene, toluene, and p-xylene) through microcomposites of NR/carboxylated styrene-butadiene rubber (XSBR) latex blend membranes (70/30) was investigated by Stephen et al. Results indicated that the blend membrane exhibited unexpected diffusion behaviour, and this was attributed to the immiscibility of the two blend... 

The thermal stability of NR and carboxylated styrene butadiene rubber (XSBR) lattices and their blends were studied by thermogravimetric methods by Stephen et The thermal degradation and ageing properties of these individual lattices and their blends were investigated with special reference to blend ratio and vulcanization techniques. As already described, as the XSBR content in the blends increased, their thermal stability was also found to increase. Among sulphur and radiation-vulcanized samples, radiation cured possessed higher thermal stability due to the higher thermal stability of carbon carbon crosslinks. 

R. Stephen et al. also studied the effect of microfillers on the thermal stability of NR, carboxylated styrene-butadiene rubber (XSBR) lattices and their 70/30 NR/XSBR blend. Microcomposites of XSBR and their blend were found to be thermally more stable than unfilled samples. ... 

Boonmahitthisud et al., prepared natural rubber/carboxylated styrene butadiene rubber (NR/XSBR) (80/20) nanocomposites containing different loadings of carbon nanotube (CNT) (0.1-0.4 phr) by a latex stage compounding method. The dynamic mechanical properties, in terms of tan 8 and E, of the neat 80/20 NR/XSBR blend and its nanocomposites were evaluated from —80 to 100 °C. Figure 21 shows the influence CNT loadings, on the tan 8 and E as a function of temperature for the nanocomposites [100].
