Abstract
| - A series of novel, well-defined, unsymmetrical poly(ethylene glycol) chains of the type X(OCH2CH2)nY (where X = protecting group; Y = nucleofuge or a different protecting group; n = 3, 6, 9,12, 15, 18, and 24) were prepared in high yields by applying orthogonal protecting groups. Thepurity of the compounds was fully verified by elemental and high-resolution mass spectrometryanalyses.
