  • structures of the polymers obtained by the solid state polymerization of diyne Triyne and tetrayne with long alkyl substituents
    Bulletin of the Chemical Society of Japan, 1991
    Co-Authors: Shuji Okada, Kikuko Hayamizu, Hiro Matsuda, Atsushi Masaki, Hachiro Nakanishi
    Abstract:

    Structures of the polymers obtained by solid-state polymerization of diyne, Triyne, and tetraynes substituted by long chain alkyl groups were investigated by solid-state 13C NMR spectroscopy. Assignment of all peaks in the spectra were made successfully, referring to those of the monomers and the polydiacetylenes of known structures. It was clearly shown that the backbone of these polymers has always the same structure of (Remark: Graphics omitted.). This fact suggests that only 1,4-addition polymerization takes place in the similar way for the diyne, the Triyne and the tetraynes, excluding many other possible addition schemes, and the tetraynes give an interesting polydiacetylene with butadiynyl substituents. This exclusive 1,4-addition can be explained in terms of topochemical control.
