Preserved Fulltext
Spherical polyphenylsilsesquioxane particles were prepared by a two-step acid-base catalyzed sol-gel process, in which various amounts of ethanol were used as a solvent to vary the concentration of phenyltriethoxysilane PhSi OEt 3 used as a starting alkoxide. The decrease in the PhSi OEt 3 concentration led to the decrease in the average molecular weight and glass transition temperature of the polyphenylsilsesquioxanes. Thus, the change of the PhSi OEt 3 concentration in the preparation of
