Silsesquioxane alicyclic acid dianhydride DDSQ
Silsesquioxane alicyclic acid dianhydride DDSQ is a bifunctionalized alicyclic acid dianhydride of double-decker silsesquioxane, which can be used as a raw material for transparent polyimide resin.
Among silsesquioxane, which is a low-dielectricity, highly heat-resistant silicon compound, double-decker (cage) silsesquioxane has a particularly bulky and rigid structure and is superior in heat resistance and mechanical strength.
Silsesquioxane Alicyclic Acid Dio Anhydride DDSQ has made it possible to use double-decker silsesquioxane (cage type) as a raw material for transparent polyimide resin by converting it into an alicyclic acid diohydride with outstanding transparency.
By combining silsesquioxane alicyclic acid dianhydride DDSQ with various diamines to make transparent polyimide resins, we expect to obtain transparent polyimide resins with high heat resistance, low dielectricity, and low linear thermal expansion.
