The present invention relates to a ω-[2-(polyalkyleneoxy)ethylthio]alkylalkoxysilane derivative and a preparation method thereof, more particularly to a ω-[2-(polyalkyleneoxy)ethylthio]alkylalkoxysilane derivative prepared by transforming a (ω-mercaptoalkyl)alkylalkoxysilane compound into a ω-(alkoxysilyl)alkylthiolate metal salt by treating it with a metallic base and performing dehalometallation at low reaction temperature using a poly(alkyleneoxy)alkyl ether halide or a poly(alkyleneoxy)bis(haloalkyl) ether to form a carbon-sulfur bond and a preparation method thereof. The novel compound of the present invention has not only a Si—OR bond but also contains a sulfur atom in the molecule, so that it can be used as monomer for synthesizing hydrophilic functional silicon polymers, source material of silicon-based surfactants and surface modifier of organic/inorganic materials. In addition, the preparation method of the compound is an economical one as the reaction can be performed at room temperature, the production yield is high and the reaction byproduct (metal halide) can be easily removed by filtration.
