| abstract |
The present application relates to novel monodisperse, gel-type or macroporous picolylamine resins which are based on at least one monovinylaromatic compound and at least one polyvinylaromatic compound and/or a (meth)acrylic compound and contain tertiary nitrogen atoms in structures of the general formula (I) n nas functional group, wheren nR 1 is an optionally substituted radical from the group consisting of picolyl, methylquinoline and methylpiperidine, R 2 is a radical —(CH 2 ) q —COOR 3 , R 3 is a radical from the group consisting of H, Na and K, m is an integer from 1 to 4, n and p are each, independently of one another, a number in the range from 0.1 to 1.9 and the sum of n and p is 2, q is an integer from 1 to 5 and M is the polymer matrix, a process for preparing them and their uses, in particular the use in hydrometallurgy and electroplating. |
