Abstract
According to the present invention there is disclosed a process for producing a fluorine-containing siloxane compound represented by the formula (3): ##STR1## wherein A is a fluorine-containing organic group represented by the formula (4): ##STR2## (wherein R.sup.1 and R.sup.2 are each independently a fluorine atom or a trifluoromethyl group, R.sup.3 is a hydrogen atom or a straight chain or branched chain hydrocarbon group having 1 to 8 carbon atoms, k is an integer of 0 to 16, m is an integer of 0 to 30, n is 0 or 1, and p is an integer of 0 to 9); r is an integer of 1 to 3; R.sup.4 is a monovalent hydrocarbon group having 1 to 6 carbon atoms; and B.sup.1 is a hydrogen atom, a methacryloxypropyl group or a vinyl group!, which process comprises reacting a fluorine-containing silane represented by the formula (1): ##STR3## (wherein R.sup.1, R.sup.2, R.sup.3, k, m, n and p have the same definitions as given above) with a chlorosilane represented by the formula (2): ##STR4## (wherein R.sup.4, B.sup.1 and r have the same definitions as given above). There is also disclosed a fluorine-containing siloxane compound of the formula (3) wherein B.sup.1 is an isocyanate-containing group.
