"Dendronized Polymers: Increasing of dendron generation by the attach-to approach Macromolecules 2000, 33, 4321-4328

Abstract Dendronization with the first generation (G1) building block 10b of the polystyrenes 13c and 14c carrying first G1 and second generation (G2), amino-terminated appendant dendrons is reported. Comparison of the 1H and 13C NMR spectra of the resulting G2 and G3 polystyrenes (15, 17a) with those recorded of the same polymers independently prepared from the corresponding G2 and G3 macromonomers 16 and 12, respectively, proved the degree of coverage to be virtually 100 %. This is the first example of a convergent synthesis of a G3 polymer which will considerably widen the synthetic access into this class of macromolecules
