Abstract

The invention relates to compounds of the formula EQU [RSiO.sub.3/2 ].sub.z (I) in which PA0 z is 6, 8 or 10; PA0 R represents the same or different radicals of the formulas EQU --CH.sub.2 CH.sub.2 --X (II), --CH(CH.sub.3)--X (III) or --O--Si(R'.sub.2)--Y (IV) PA0 with the proviso that up to z-1 of the radicals can also be radicals of the formula --O--SiR'.sub.3, in which X represents a monovalent radical or one half of a divalent radical of the formulas ##STR1## R' represents the same or different C.sub.1 - to C.sub.6 -alkyl, C.sub.1 - to C.sub.6 -alkoxy or phenyl radicals; PA0 R" represents the same or different C.sub.1 - to C.sub.18 -alkyl radicals, which can be substituted by radicals of formulas (V) or (VI); PA0 R'" represents the same or different divalent C.sub.1 - to C.sub.18 -hydrocarbon radicals, preferably alkylene and/or phenylene radicals and/or radicals of the formula EQU --(R'.sub.2 SiO).sub.n --; PA0 Z represents a halogen atom or an N-bonded amino radical, that is an NH.sub.2 radical, an N-piperidinyl, n-piperazinyl or N-morpholinyl radical or a C.sub.1 - to C.sub.6 -N-monoalkylamino or a C.sub.1 - to C.sub.6 -dialkylamino radical; PA0 Y represents a hydrogen atom,…
