Hydrogen containing phenyl silicone resin was prepared through hydrolysis polycondensation process , by using phenyltrimethoxyl silane , tetramethyldisiloxane and hexamethyl disiloxane as start ma-terial , and acidic cation exchange resin as catlyst .The structure of the polymer was characterized through Fourier Transform Infrared Spectroscopy ( FTIS ) and 1H Nuclear Magnetic Resonance Spectroscopy (1HNMR), and the preparation process and the curing properties were also studied .The results showed that the hydrolysis extent of the methoxyl reached 99.9%, but the polycondensation of Si-OH was not complete, and the residue was about 0.57%.The cured polymer had better mechnical performance when used the silicone resin with moderate hydrogen content , 0.37%, and with moderate viscosity , 722 mPa· s.
