To study NR mesostructure (macromolecular structure + aggregates or gels) (Figure 1), the NR sample is placed in a good solvent of polyisoprene (cyclohexane, toluene or tetrahydrofuran). In addition to a soluble fraction, there is always an insoluble fraction called macrogel (Figure 1) or gel depending on the authors [1-4]. The gel fraction of NR not only consists of an insoluble fraction or ma...
