Synthesis of a new kind of carbohydrate-modified polysiloxanes and its morphological transition of molecular aggregates in water

摘要: Abstract Allylamides of gluconic acid were synthesized by the reaction allylamine with lactones using dimethyl formamide as a solvent. In this reaction, hydroxyl groups protected trimethylsilyl via three different pathways that connect sugar units onto polysiloxane chains. A series well-defined polysiloxanes pendent prepared hydrosilation trimethylsilyl-protected allylamides hydric in presence Platinum dioxide catalyst. The catalytic activity and selectivity discussed detail. All products characterized FT-IR, 1 H NMR, 13 C NMR spectroscopy, respectively. Furthermore, shapes molecular aggregates target polymers water studied transmission electron microscopy, which reveals transitions micelles- morphologies from spheres to vesicles can be controlled adjusting hydrogen content primary materials or changing initial solvents.
