Abstract
Official abstract text for this publication.
Disclosed are a method for polymerizing polysilsesquioxane from a trialkoxysiloxane monomer, including: preparing an aqueous organic solution including a trialkoxysiloxane monomer, an organic solvent, water and a catalyst; and selectively preparing a polysilsesquioxane with a cage structure or a polysilsesquioxane with a ladder structure by adjusting the amount of the organic solvent or water in the aqueous organic solution, and a polysilsesquioxane with a cage structure or a polysilsesquioxane with a ladder structure prepared therefrom.
