| 摘要 |
The present invention relates to spherical polymer tertiary or secondary organosiloxaneamine compounds of units (I) in which R1 and R stand for a group (II) wherein R4 is an alkylene group and the oxygen atoms are saturated by additional groups (II), optionally with the incorporation of cross-linking agents, R3 equals R1 and R or stands for a hydrogen, an alkyl, cycloalkyl, or the benzyl group. Further objects of the present invention are a process for producing the compounds in spherical form as well as the use of these products for the removal of acids from liquids and gases, and for the adsorption of gaseous organic compounds. |
