Carbohydrate-modified polysiloxanes have been presented several times within the last decade. In this work, a new route to carbohydrate-segmented polysiloxanes is presented. A series of allyl-group-containing bifunctional carbohydrate derivatives was synthesized and reacted with hydrodimethylsilyl-terminated polysiloxane in hydrosilylation reactions with Speier's catalyst. The carbohydrate monomers and the resulting materials were fully characterized with H-1 and C-13 NMR spectroscopy. (c) 2005 Wiley Periodicals, Inc.
