Abstract
Abstract A fluorine containing organosilicon compound represented by the following general formula: ##STR1## wherein R represents an alkyl group or an aryl group, a is an integer of 1 to 7, b is an integer of 2 to 8, and c is an integer of 1 to 3. This compound is useful as a surface treating agent for silicas, an adhesive improver for resists, an oil or water-repellent treating agent, and a raw material for synthesis of various silicone compounds.
