Polysiloxanes Grafted with Mono(alkenyl)Silsesquioxanes-Particular Concept for Their Connection

摘要: Herein, a facile and efficient synthetic route to unique hybrid materials containing polysiloxanes mono(alkyl)silsesquioxanes as their pendant modifiers (T8@PS) was demonstrated. The idea of this work apply the hydrosilylation reaction tool for selective attachment mono(alkenyl)substituted silsesquioxanes (differing in alkenyl chain length, from -vinyl -dec-9-enyl types inert groups iBu, Ph at inorganic core) onto two various amount Si-H units. protocol, determined confirmed by FT-IR situ NMR analyses, optimized ensure complete consumption along with avoidance side-products. A series 20 new compounds high yields β-addition selectivity obtained characterized spectroscopic methods.
