Sulfur-Cured Natural Rubber Elastomer Networks: Correlating Cross-Link Density, Chain Orientation, and Mechanical Response by Combined Techniques.
Macromolecules 46, 889-899 (2013).
We present a combination of independent
techniques in order to characterize vulcanized natural rubber
elastomer networks. We combine solid state proton multiplequantum
NMR, equilibrium swelling, mechanical experiments,
and in-situ tensile X-ray scattering measurements, all of them
giving access to the segmental orientation effects in relation to the
cross-linking of the systems. By means of the combination of
these techniques, we investigate a set of unfilled natural rubber
networks with different levels of cross-linking. The relevance of
this work is the application of this approach in order to study the
reinforcement effect in filled elastomers with nanoparticles in a
