Abstract
Polysiloxanes are unique hybrid inorganic and semi-inorganic polymers that have a wide range of applications in industries. In this study, we report a facile and efficient approach to prepare functional polysiloxanes via thiol–ene reaction. The functional polysiloxanes were characterized and confirmed by 1H NMR, 13C NMR, FT-IR, GPC, TGA and DSC. Influence of thiol and vinyl structure over reaction rate was analyzed. The proportion of α- and β-addition product was also determined by 1H NMR. GPC analysis showed that the molecular-weight distribution of polysiloxanes cannot be disturbed in thiol–ene reaction.
