Polychloroprene. I. Etude de la microstructure par RMN 1H

The microstructure of polychloroprenes was studied by ¹H-NMR at high field (350 MHz). An examination with two solvents, CDCl₃ and C₆D₆, was necessary to show all the addition modes. The complementary information obtained made possible the quantitative determination of head-to-tail, head-to-head, tail-to-tail, trans-1–4, and cis-1–4, 1–2, and 3–4 additions.
