Abstract
Provided are chains of precise length and methods for their preparation. These chains are formed by the reaction of a derivative of a diacid and a diamine in a stepwise manner on a support. One of the reactants contains a water soluble oligomer, preferably polyethylene glycol. These chains are then used to chemically modify target macromolecules such as biologically important polypeptides.
