Latex state NMR spectroscopy and field gradient fast magic angle spinning solid state NMR spectroscopy were used for structural characterization of vulcanized butadiene rubber and vulcanized natural rubber. High resolution NMR spectra for elastomers were achieved either through Brownian motion of a latex dispersion or fast magic angle spinning for a solid. Sequence distribution of cis-1,4-, trans-1,4- and 1,2-butadiene units was investigated for polybutadiene through latex state NMR spectroscopy. Crosslinking junctions of vulcanized natural rubber were analyzed by field gradient fast magic angle spinning solid state NMR spectroscopy.
