CASCADE POLYMERS WITH IODINE AROMATIC COMPOUNDS

摘要

Iodine-containing dendrimeric polymers of general formula I A-(X)b ~~~(I), in which A stands for a nitrogen-containing nucleus of basic multiplicity b, whereby b stands for numbers 1 to 8 and X stands for a radical that consists of (see fig II) reproduction units S and at most 2" imaging radicals Z, in which n determines the number of generations and stands for numbers 1 to 10, S and Z have various meanings, are valuable x-ray diagnostic agents.
