PURPOSE: To obtain the subject new derivative by reacting a polyfluoroalkylstyrene with a silane derivative by using a platinum catalyst, excellent in heat resistance, water repellence, insulating properties, oil resistance, low-temperature resistance and solvent resistance, useful as a raw material for a silicone product, etc. CONSTITUTION: This new polyfluoroaralkylsilane derivative is shown by formula I (X1 to X3 are each a halogen, a 1-5C alkyl or a 1-5C alkoxy). The compound is excellent not only in heat resistance, water repellence and insulating properties but also in oil resistance, low-temperature resistance and solvent resistance, useful as a raw material for a silicone product, a raw material for a filler for high-performance liquid chromatography, etc. The compound is obtained by reacting a polyfluoroalkylstyrene of formula II with a silane derivative of formula III (e.g. chlorodimethylsilane, etc.) by using a platinum catalyst (e.g. platinum-divinyltetramethyldisiloxane complex, etc.) under heating at 80 deg.C for 3 hours and purifying the resultant substance by vacuum distillation. |
