Abstract:
1. A flowable, non-cross-linked polyorganosiloxane having the following structural units as well as, optionally, one or several units having the following structure: whereby said structural units may be distributed over the polysiloxane chain in any desired way; whereby the two terminal groups of the polyorganosiloxane are formed by units having the formula wherein all radicals Z present independently of one another represent CH 3 or a radical having the formula (I) or a radical of said formula (I), in which a additional radical R, where the additional radical R is not hydrogen is bonded to one or several of the nitrogen atoms present, so that said nitrogen atoms are in the quaternized form; whereby X represents CH whereby all radicals R independently of one another represent hydrogen or an alkyl radical with 1 to 8 carbon atoms; all radicals R 1 , R 4 and R 5 independently of one another represent H or CH 3 ; all radicals R 2 independently of one another represent a linear or a branched alkylene radical with from 2 to 6 carbon atoms, and in each unit —OCHR 4 —CHR 5 not more than one of the radicals R 4 and R 5 represent CH 3 ; b is a number of from 2 to 6, c is a number of 0 or 1; and d is a number of from 2 to 25; whereby all radicals Y present independently of one another represent a radical of the formula (I), in which a additional radical R, where the additional radical R is not hydrogen is bonded to all nitrogen atoms present, so that all nitrogen atoms are present in the quaternized form, or whereby all radicals Y independently of one another represent a radical of the formula (III) or (IV) or (V)  —R 2 —COOH  (IV) whereby B is the monovalent radical derived from ethylene oxide or a radical having the formula or whereby all radicals Y independently of one another represent whereby the polysiloxane contains at least one radical of the formula (I), in which at least one additional radical R, where the additional radical R is not hydrogen is bonded to at least one nitrogen atom and said nitrogen atoms is therefore present in the quaternized form; whereby in case the polysiloxane does not contain any radical of the formula (II), at least one of the radicals Y is a radical having the formula (III), (IV) or (V), or a radical of the formula (I) in which a further radical R which is not hydrogen is bonded to all nitrogen atoms; whereby in case the polysiloxane does not contain any radical of the formula (II), a further radical R, the latter not being hydrogen, is bonded to all nitrogen atoms present in the polysiloxane, so that all nitrogen atoms are present in the quaternized form; whereby in case the polysiloxane contains one or several radicals X of the formula (II) all radicals Y represent CH and whereby the anions associated with the quaternized nitrogen atoms are methyl sulfate anions, chloride anions, benzene sulfonate anions, or toluene sulfonate anions.
