Volume fraction of rubber in the swollen gel.
Volume fraction of rubber, Vr was calculated using the following equation [28] (1).
Volume fraction of rubber, V r, was calculated using the following equation [20] (1).
This leads to better curing as observed in the previous experiments and higher value of volume fraction of rubber (V r) as well as crosslink density.

Swelling tests were conducted by measuring the filler-filler interaction, swelling ratio, cross-link density, volume fraction of rubber, and shear modulus of the rubber composites.
The volume fraction of rubber in the swollen network (V r) for the studied rubber composites follows the trend: Sample B > Sample E > Sample C > Sample D > Sample A > Sample F (Table 2).
where, Vr is volume fraction of rubber in the swollen gel, D the de-swollen weight of the composites, F the fraction insoluble, T the initial weight of the sample, and A0 the amount of solvent imbibed.
