Dendro Acid-PEG-Dendro Acid or Hyperbranched Acid-PEG-Hyperbranched Acid consists of a linear PEG10k core with two hyperbranched, dendritic wedges at both ends of the PEG chain. This series of products feature linear PEG functionalized with a bisMPA dendrimer wedge with an average number of functional end groups (such as carboxylic acid).  The hyperbranched structure is described as pseudo-generations of dendrimers G3, G4, G5 and G6 having 16, 32, 64, and 128 end functional groups, respectively. The MW for the entire molecule for G3, G4, G5 and G6 is 13,200, 16,700, 29,000 and 37,400 gram per mole. The MW of entire molecule is calculated from the MW of the linear PEG core combined with the number of dendritic structure and the functional groups. Products are fully characterized by HNMR CNMR and SEC (GPC). Full analytical data and ChemDraw structure of each generation are available upon request.
