Abstract
Spherical, polymeric, tertiary or secondary organosiloxane amine compounds comprising: ##STR1## units in which R.sup.1 and R.sup.2 stand for a group: ##STR2## R.sup.4 is an alkylene grouping and the oxygen atoms are saturated by silicon atoms of other groups (II), with the optional inclusion of cross-linking agents, R.sup.3 is equal to R.sup.1 and R.sup.2 or stands for hydrogen, an alkyl, cycloalkyl or the benzyl group. Also disclosed is a method for the preparation of the compounds in spherical form and the use of these products for removing acids from liquids and gases as well as for the adsorption of gaseous organic compounds.
