Investigation of the controlled release of tertiaryalcoholsfrom the surface of dendrimers and “stylomers” as polymer model systems (see scheme) showed that the polarity of the conjugates and structural modifications in close proximity to the release unit have a stronger influence on the rates of hydrolysis than the size (generation) or shape (linear or spherical) of the macromolecules.

naturally occurring polyamines, the practical synthesis of a series of substituted homo- and hetero-dimers of linear polyamines, spermine and norspermine succinamides and branched polyamines is achieved via 1,4-Michael addition of acrylonitrile and then hydrogenation of the nitrile functional groups to primaryamines. The most charged analogue, a branched polyamine carrying eight positive charges at
