O. Kuznetsova et al., Synthesis and some properties of poly(alkylene phosphorothioate)s preparedfrom the corresponding poly(alkylene H-phosphonate)s, J BIOACT C, 14(3), 1999, pp. 232-242
Several high molecular weight poly(alkylene phosphorothioate)s were synthes
ized by reacting poly(H-phosphonate)s with sulfur. The molecular weight of
the resulting polymers are similar to the respective starting poly(alkylene
H-phosphonate)s indicating that during sulfurization process no chain degr
adation occurred. The structure of poly(alkylene phosphorothioate)s was con
firmed by the analysis of H-1, C-13 and P NMR spectra.
