| 摘要 |
The present invention relates to novel monodisperse or heterodisperse, gel-form or macroporous, moderately or strongly basic anion exchangers based on at least one monovinylaromatic compound and at least one polyvinylaromatic compound, which contain both carboxyl groups COOR<SUB>3</SUB> and -(CH<SUB>2</SUB>)<SUB>m</SUB>NR<SUB>1</SUB>R<SUB>2</SUB> and/or -(CH<SUB>2</SUB>)<SUB>m</SUB>NR<SUB>1</SUB>R<SUB>2</SUB>R<SUB>4</SUB> groups, to a process for their preparation and to their use, especially to the use of the monodisperse anion exchangers in hydrometallurgy. |
