Syntheses of cage octasilicate polymers
Source abstract
Abstract
Octakistetramethylammonium octasilsesquioxane (Q 8 TMA ) was synthesized from water glass (No. 3) by neutralization, extraction with tetrahydrofuran, and condensation reaction using tetramethylammonium hydroxide. Octakisdimethylsilyl octasilsesquioxane (Q 8 DMS ) was synthesized by the reaction of Q 8 TMA with chloro(dimethyl)silane. An all-siloxane-type cage-containing polymer was synthesized by the reaction of Q 8 DMS with water by using diethylhydroxylamine as a catalyst. The reaction of Q 8 DMS with diphenylsilanediol was carried out to provide oligomers. This reaction was carried out by the addition of Q 8 DMS twice to isolate a cage-containing polymer with a weight-average molecular weight of 18,000.
