was prepared via the corner capping reaction of incompletely condensed silsesquioxanes
(C5H9)7Si7O9(OH)3
with vinyltrichlorosilane.VinylPOSS was characterized by FTIR
1H NMR
29Si NMR
13C NMR
elemental analysis
WAXD and TGA.The yield of VinylPOSS increased with reaction time
when vinyltrichlorosilane reacted with (C5H9)7Si7O9(OH)3 for 10 h
the yield was 90%.VinylPOSS has good solubility in weak polar solvent
and it shows good thermal stability
its temperature with 5% decomposition is 283℃ and the temperature with 56% residue is 800℃.The reactivity of VinylPOSS with high hydrogen-containing silicone fluid (HHSF) was investigated.It can be reacted with HHSF by Michael additions at both α- and β- positions
