Title:
A METHOD FOR PREPARING A POLYSILSESQUIOXANE OF A CONTROLLED STRUCTURE AND POLYSILSESQUIOXANE PREPARED BY THE SAME
Document Type and Number:
WIPO Patent Application WO/2012/023652
Kind Code:
A1
Abstract:
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.
