| Abstract | {Random styrene-ethylene copolymers have been synthesized by the hydrogenation of styrene-butadiene copolymers. The samples were characterized by 13C NMR spectroscopy, X-ray powder diffraction, thermal analysis, and Fourier transform IR (FTIR) spectroscopy. In the 13C NMR spectra, the resonance of the methylene carbon next to a methine bearing a phenyl group presents splitting due to its diastereotopic positions with respect to the phenyl substituents of the second and third inserted styrene units. A definitive assignment of the resonances of the SEES sequences (S = styrene |
