Abstract

Abstract This invention relates to fluoroalkyloxyalkyl diorganopolysiloxanes having the general formula ##STR1## where R 1 represents fluoroalkyloxyalkyl groups of the general formula --(CH.sub.2).sub.a --O--C.sub.b R.sub.2b H in which the hydrogen atom is in the beta position to the ether oxygen, a is 2, 3 or 4; b is an integer having a value of from 1 to 6; R 2 represents an alkyl group having from 1 to 8 carbon atoms whose terminal units may also contain an amino or a thiol group, or an alkenyl group having 2 or 3 carbon atoms, or an aryl group having from 6 to 8 carbon atoms or hydrogen; R 3 represents the group having the formula --(CH.sub.2).sub.c --C.sub.d F.sub.(2d-e+l) Hal.sub.e , in which Hal represents a terminal chlorine, bromine or iodine atom, c is 2, 3 or 4; d is an integer having a value of from 1 to 18; e is 0 or 1; R 4 , R 5 and R 6 are the same as R 2 ; X and Y are the same or different and represent condensable terminal groups or trialkylsiloxy groups in which the alkyl groups have from 1 to 6 carbon atoms; m has a value of from 0.05 to 0.9; n has a value of from 0 to 0.6; and p has a value of from 0.1 to 0.8 with the proviso that the sum of m+n+p=1.
