Abstract
Abstract A fluorine-containing organosilicon compound represented by Formula (I): ##STR1## wherein R 1 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms; R f represents a fluorine-containing group represented by the formula: C p F 2p+1 -, where p is an integer of 3 to 6, ##STR2## where q is an integer of 1 or 2, or ##STR3## where q is as defined above; m is an integer of 0 to 2; and n is an integer of 3 or 4. This novel compound is useful for the preparation of fluorosilicone polymers having a good thermal resistance, chemical resistance and weathering resistance.
