An organosilicon compound having an amino group is provided. This compound is represented by the following general formula (1): wherein R1 and R2 respectively represent an unsubstituted or substituted aliphatic monovalent hydrocarbon group containing 1 to 10 carbon atoms with the proviso that the R1 and R2 may together form a ring with the nitrogen atom to which they are bonded, and that R1 and R2 may contain a heteroatom; R3 and R4 independently represent an unsubstituted or substituted monovalent hydrocarbon group containing 1 to 10 carbon atoms; and n represents an integer of 0 to 2. Use of this compound enables production of a polymer product having excellent mechanical properties, high heat resistance, and high transparency. The solution of this compound is stable, and can be stored for a long time, and when used for a polymer modifying agent, it facilitates introduction of amino group and hydroxy group.

Alkoxysilane compounds having two fluoroalkyl groups and represented by the 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 are imparted to the inorganic material. The alkoxysilane compounds are easily purified, owing to enhanced volatility by the branched structure.
