Abstract: Organopolysiloxanes are described with the same or different units of the formula: (O3/2Si-R1-SO3-)xMx+(1) in which R1 is alkyl, x is dependent on M and signifies a number from 1 to 4 and M represents hydrogen or a mono- to tetravalent metal ion and the valences of the oxygen atoms are saturated by silicon atoms of other groups of the formula (1), optionally by inserting cross-linking silicon, titanium or aluminum compounds and/or by di-, tri- and tetrasulfide units of the formula: (2) in which the substituents R1 have the same meaning as in (1) and can be the same or different, wherein the ratio of the sum of silicon atoms in (1) and (2) to the silicon, titanium and aluminum atoms of the cross-linking agent ranges from 1:0 to 1:10. Furthermore, the method of obtaining the organopolysiloxanes containing sulphonate groups and the use thereof as strongly acidic cation exchangers are described.

Abstract: Polymeric tertiary and secondary amines as described with a silica-type backbone, comprising units of the formula: (1) in which R1 and R2 represent a group (2) R4 is alkylene and the free valencies of the oxygen atoms are saturated by silicon atoms of further groups (2), if appropriate with incorporation of crosslinking agents, R3 has the same meaning as R1 and R2, or it represents hydrogen, alkyl, cycloalkyl or benzyl. Also disclosed are processes for preparing the polymeric tertiary and secondary amines and the use of these materials for removing acids from liquids and gases.

Abstract: The subject of the invention is a process for the manufacture of (iodoorganyl)alkoxysilanes of the general formula: (1) in which R1 is an alkylene group, R2 is an alkoxy group and R3 and R4 an alkoxy group and/or an alkyl or aryl group, whereby the chlorine or bromine compound corresponding to that of formula (1) is caused to react with stoichiometric to double molar quantities of an inorganic iodine donor in the presence of 0.01-5 mol % of an organic substituted onium salt of nitrogen, phosphorus, arsenic or antimony or an organic substituted sulfonium salt or a crown ether as catalyst, in certain solubilizing agents.
