Synthesis of Bis(4-Anilinylmethylsilyloxy)-Octaphenylsilsesquioxane-Modified Thermosetting IMIDE Oligomers
Abstract
A series of Bis(4-Anilinylmethylsilyloxy)-octaphenyl-silsesquioxane-modified thermosetting imide oligomers were prepared and the structure were characterized by FTIR and NMR. Bis(4-Anilinylmethylsilyloxy)-Octaphenyl-silsesquioxane was synthesized using a previously reported method and was reacted with 6-FDA, ODA and PEPA monomers to produce oligomers with 0.0, 11.9, 18.8, 23.3, 26.4, and 28.8 weight percent Si10O14. FTIR analysis was performed to ensure complete imidization. NMR spectra (1H, 13C and 29Sil) were collected and integrated to ensure the target chain length was obtained.
