Methylphenyldimethoxysilane and diphenyldiethoxysilane were co-hydrolyzed with dimethyldimethoxysilane, respectively, and equilibrium polycondensation was catalyzed by trifluoromethanesulfonic acid to synthesize two different phenyl moles. Fractions of phenyl silicone oil. The effects of phenyl molar fraction and molar mass on the thermal stability, refractive index and rheological properties of phenyl silicone oil were studied. The results show that the refractive index of phenyl silicone oil increases with the increase of the phenyl mole fraction. When the phenyl mole fraction is 25% to 30%, the thermal stability of diphenyl silicone oil is better.
