ABSTRACT:
Higher generation radially layered copolymeric dendrimers having a hydrophilic poly(amidoamine) or a hydrophilic poly(propyleneimine) interior and a hydrophobic organosilicon exterior are prepared by first reacting a hydrophilic dendrimer having --NH.sub.2 surface groups with an organosilicon compound, and then hydrosilating the resulting copolymeric dendrimer with another organosilicon compound in the presence of a noble metal catalyst. In an alternate embodiment, the radially layered copolymeric dendrimers are prepared by reacting a hydrophilic dendrimer having --NH.sub.2 surface groups directly with an organosilicon dendron or organosilicon hyperbranched polymer.
