A COMPOSITION COMPRISING A MONOMER FOR POLYMERIZING BRANCH-TYPE SILSESQUIOXANE POLYMER, BRANCH-TYPE SILSESQUIOXANE POLYMER SYNTHESIZED FROM THE SAME AND A METHOD FOR SYNTHESIZING THE SAME

WIPO Patent Application WO/2012/036510

A3

A monomer composition for polymerizing a branch-type silsesquioxane polymer is disclosed. The monomer composition includes hydroxy-substituted cyclic siloxane in a solvent, and the hydroxy-substituted cyclic siloxane includes stereoisomers of cyclic siloxane of cis, trans, random and twist structures at controlled ratios. Also disclosed are a branch-type silsesquioxane polymer synthesized by polymerizing the monomer composition for polymerizing a branch-type silsesquioxane polymer, and a method for synthesizing the same. In accordance with the disclosure, the isomers can be isolated stably at desired ratios. The isolated isomers may be polymerized into polymers of various types. Since the polymers exhibit low dielectric property, they may be utilized as low dielectric materials.
