Abstract

Spherical, polymeric organosiloxane ammonium compounds are disclosed with a silica-like skeleton consisting of: ##STR1## units in which R.sup.1 and R.sup.2 stand for a group ##STR2## in which R.sup.5 is alkylene the oxygen atoms are saturated by silicon atoms of other groups (II) with the optional inclusion of cross-linking agents, R.sup.3 has the meaning of R.sup.1 and R.sup.2 or stands for hydrogen, alkyl, cycloalkyl or benzyl, R.sup.4 is hydrogen or alkyl, cycloalkyl, benzyl, allyl, propargyl, chloroethyl, hydroxyethyl or chloropropyl, X stands for a monovalent to trivalent anion of a protonic acid which forms stable salts with amine bases and x can be a number from 1 to 3.
