摘要：
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 H-1 NMR, C-13 NMR, FT-IR, GPC, TGA and DSC. Influence of thiol and vinyl structure over reaction rate was analyzed. The proportion of alpha- and beta-addition product was also determined by H-1 NMR. GPC analysis showed that the molecular-weight distribution of polysiloxanes cannot be disturbed in thiol-ene reaction. (C) 2013 Elsevier Ltd. All rights reserved.
