The separation of polyethylene glycols (PEGs) into single homologs by reversed-phase chromatography is investigated experimentally and theoretically. used core–shell column shown to achieve the baseline PEG up molar weights at least 5000 g/mol. A detailed study performed elucidating role operating conditions, including temperature, eluent composition, degree polymerization polymer. Applying Mar...

Dendrimers are macromolecular hyperbranched nano-structures, which properties mainly driven by the type of their terminal functions. This paper reports synthesis dendritic structures built from difunctional polyethylene glycols (PEGs) used as core. Three different PEG lengths have been used: PEG300 (ca 6 CH2CH2-O units), PEG1000 22 and PEG2000 45 units). The first level branching units is based...
