    摘要: An organopolysiloxane of the formula ##STR1## in which x=0 to 500,y=5 to 500,z=5 to 500,R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 independently of one another, represent a saturated and/or unsaturated, optionally also branched alkyl radical having 1 to 4 C atoms, and/or an aryl radical having 6 to 9 C atoms, which may also be optionally alkyl-substituted,R.sub.7 represents an alkyl radical having 6 to 18 C atoms,and in which in each case at least 3% of the radicals bonded to Si are R.sub.7 and H. They are reactive with substrates and thus wash-resistant.
