ORGANOPOLYSILOXANE COPOLYMER, ITS PREPARATION, METHOD FOR REMOVING DISSOLVED METAL FROM AQUEOUS OR ORGANIC SOLUTION, AND METHOD FOR ADSORPTION OF GASEOUS ORGANIC COMPOUND

摘要

The invention relates to organosiloxane-amine copolycondensates as random or block copolycondensates or mixtures thereof of …IMAGE… and X - R4 (II). …??R1 to R4 is …IMAGE…. …??R5 is directly bonded to the nitrogen atom or the single-bonded radical X and is an alkylene group, cycloalkylene group or …IMAGE… or …IMAGE…. …??In these formulae, n is 1 to 6 and m is 0 to 6. The free valences of the oxygen atoms bonded to the silicon atom are saturated by silicon atoms of other groups of the formula (III), if appropriate with the incorporation of cross-linkers. X stands for -NH2, -NH-(CH2)2-NH2, -NH-(CH2)2-NH-(CH2)2-NH2, -Cl,-Br,-I,-SH,-P(C6H5)2, …IMAGE… where R" is H or an alkyl group. Preparation processes and the use of the process products for the removal of dissolved metals from solutions or for the adsorption of organic solvents are also given.
