Abstract
Disclosed are alkoxysilane compounds having two fluoroalkyl groups and represented by the following general formula (1):wherein Rf and Rf′ are each a fluoroalkyl group of 1 to 10 carbon atoms, R1 is a hydrogen atom or an aliphatic monovalent hydrocarbon group of 1 to 6 carbon atoms, R2 and R3 are each methyl group or ethyl group, X and Y are each an ether linkage or an ester linkage, a and b are each 0 or 1, m, n and p are each an integer of 0 to 6, q is an integer of 1 to 6, and r is an integer of 0 to 2. By treating an inorganic material with the alkoxysilane compound having ether linkage and two fluoroalkyl groups, high water and oil repellency and high sliding properties can be imparted to the inorganic material. The alkoxysilane compounds can be easily purified, owing to enhancement of volatility by the branched structure.
