5. This terminology was adopted as an extension of present nomenclature which refers to present radial branched systems as “star polymers.” It should be noted that some scientists refer to the present systems as “cauliflower polymers.” (See ref 1.)

10. Statistical analysis shows that the mole fraction of unbridged dendrimer species is given by: where: P-1/(4Y- 1) andXis the moles of ethylene-diamine per mol of ester terminal group in the dendrimer. The exponential-exponential form of the above equation shows the strong dependence of f0on G.Therefore, very highXvalues (lowP)are essential for the higher generations, to assure unbridged, highly monodispersed dendrimers. A complete description with experimental verification of these statistical predictions will appear elsewhere (S. Martinet al.)
