13C‐NMR sequence analysis. 19. Anionic copolymerization of γ‐butyrolactam, δ‐valerolactam, and caprolactam at low temperatures
TL;DR: In this article, copolymerization of pyrrolidone-2 with azepinone was studied in bulk at 30 or 45°C and the resulting copolyamides were analyzed by means of 22.63MHz 13C-NMR spectra.

Secondary structure of peptides, 10. FT-IR and 13C NMR CP/MAS study on tacticity and secondary structure of poly(D,L-leucine)s†
TL;DR: In this paper, a series of poly (L-leucine)s with average degrees of polymerization in the range between 10 and 100 were prepared by polymerization of N-carboxyanhydride (NCA) or D,L-Leu-NCA.
