- 2. The lubricant of claim 1, wherein R.sup.2 is an alkyl group having from 1 to 8 carbon atoms and further contains terminal units selected from the group consisting of an amino group and a thiol group.
- 3. The lubricant of claim 2, wherein R.sup.4, R.sup.5 and R.sup.6 are each selected from an alkyl group having from 1 to 8 carbon atoms and further contains terminal units selected from the group consisting of an amino group and a thiol group.
- 4. The lubricant of claim 1, wherein R.sup.2 is hydrogen and R.sup.4, R.sup.5 and R.sup.6 are each selected from an alkyl group having from 1 to 8 carbon atoms and further contains terminal units selected from the group consisting of an amino group and a thiol group.
- 5. An antifoam containing a diorganopolysiloxane of the formula ##STR4## where R.sup.1 represents fluoroalkyloxyalkyl groups of the formula
- --(CH.sub.2).sub.a --O--C.sub.d F.sub.2b H
- in which the hydrogen atom is in the beta position relative to the ether oxygen; a is 2, 3 or 4; b is an integer of from 1 to 6; R.sup.2 is selected from the group consisting of an alkyl group having from 1 to 8 carbon atoms, an alkenyl group having 2 or 3 carbon atoms, an aryl group having 6 to 8 carbon atoms and hydrogen; R.sup.3 represents the group
- --(CH.sub.2).sub.c --C.sub.d F.sub.(2d-e+1) Hal.sub.e,
- where Hal represents a terminal halogen group selected from the class consisting of chlorine, bromine and iodine; c is 2, 3 or 4; d is an integer having a value of from 1 to 18; e is 0 or 1; R.sup.4, R.sup.5 and R.sup.6 are each selected from the group consisting of an alkyl group having from 1 to 8 carbon atoms, an alkenyl group having 2 or 3 carbon atoms, an aryl group having 6 to 8 carbon atoms and hydrogen; X and Y are each selected from the group consisting of condensable terminal groups and 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.
- 6. The antifoam of claim 5, wherein R.sup.2 is an alkyl group having from 1 to 8 carbon atoms and further contains terminal units selected from the group consisting of an amino group and a thiol group.
- 7. The antifoam of claim 6, wherein R.sup.4, R.sup.5 and R.sup.6 are each selected from an alkyl group having from 1 to 8 carbon atoms and further contains terminal units selected from the group consisting of an amino group and a thiol group.
- 8. The antifoam of claim 5, wherein R.sup.2 is hydrogen and R.sup.4, R.sup.5 and R.sup.6 are each selected from an alkyl group having from 1 to 8 carbon atoms and further contains terminal units selected from the group consisting of an amino group and a thiol group.
