Abstract
Organopolysiloxanes in which two polysiloxane chains are bonded via a divalent radical can be obtained by reaction of cyanuric halides with organopolysiloxanes which contain primary amino groups in substituents. The divalent radical contains 1,3,5-triazine rings, to which a halogen atom is still bonded. The organopolysiloxanes thus obtained are suitable for soft handle treatment of fiber materials. In particular, textile sheet-like structures which comprise cellulose fibers can thereby be given a soft handle and improved permanence of the treatment effects with respect to washing processes.
Claims3
An organopolysiloxane having the structure
- A-E-A
- in which
- E represents a divalent radical of the general formula (I) ##STR19## in which Hal represents Cl or F, y is in each case a number from 2 to 4 and a is in each case 0 or 1, in which the radicals A independently of one another represent a monovalent radical of the general formula (II) ##STR20## in which p is a number from 0 to 800, q is a number from 0 to 800 and p+q is a number from 15 to 800, in which all the radicals R.sup.3 present independently of one another in each case represent a radical R or -E-A or ##STR21## in which z is a number from 5 to 25, in which all the radicals R independently of one another represent an alkyl radical having 1 to 4 C atoms or the phenyl radical, R.sup.4 represents --OSiR.sub.2 R.sup.1 or R, in which R.sup.1 represents R, OR or OH, and in which all the radicals R.sup.5 present independently of one another represent H or CH.sub.3.
