title = "Large-scale production of polypropylenimine dendrimers",
abstract = "Th synthesis and characterization of a new series of polypropylenimine (I) dendrimers is reported. Using a repetition of the sequence of a Michael addn. to a primary amine, followed by a heterogeneously catalyzed hydrogenation, ultra-pure polypropylenimine macromols. with mol. wts. £6912 are synthesized. The reaction sequence allows the prepn. of these dendrimers at very large scales, while the availability of a simple purifn. in the sequence affords ultra-pure samples. The I dendrimers are fully characterized; apart from the first 0.5 generation they are all oils, possess a glass transition temp. of -90° to -40°, and are unexpectedly stable. Their intrinsic viscosity drops after generation 4.",
