Hiller, W.; et al. Prog Polym Sci 2014, 39, LC-NMR is aimed at the analysis of the molecular heterogeneity of complex macromolecular mixtures, such as molar mass, chemical composition and molecular microstructure.

Hiller, W.; et al. Prog Polym Sci 2014, 39, The comonomers could be efficiently distinguished by NMR due to the OCH 3 signal of PMMA at 3.59 ppm and the OCH 2 signal of P n BuMA at 3.95 ppm. The chemical composition could be evaluated from the OCH 3 and OCH 2 signal intensities.

Tashiro, K.; et al. Macromolecules 2014, 47, The purpose is to investigate the hierarchical structure changes occurring in the stress-induced phase transition phenomenon of uniaxially oriented polymer film.

Tashiro, K.; et al. Macromolecules 2014, 47, The stress-induced α−β transition was found to occur not only with the remarkable changes in the molecular chain conformation and chain packing mode in the crystal lattice, but also with the large and reversible change in the lamellar stacking structure.
