Synthesis and characterization of α-butyl-omega-{3-[2-hydroxy-3-(N-methyl-N-hydroxy- ethylamino)propoxy]propyl}polydimethylsiloxane



A novel synthesis path for the monotelechelic polydimethylsiloxane with a diol-end group, α-butyl-omega-{3-[2-hydroxy-3-(N-methyl-N-hydroxyethylamino)propoxy]propyl}polydimethylsiloxane, is described in this article. The preparation included three steps, which were anionic ring-opening polymerization, hydrosilylation, and epoxy addition. The structure and polydispersity index of the products were analyzed and confirmed by FTIR, 1H NMR, 13C NMR, H[BOND]H, and C[BOND]H. Correlated Spectroscopy and gel permeation chromatography. The results demonstrated that each step was successfully carried out and the targeted products were accessed in all cases. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
