| dc.description | A new, simple and general approach for the end-functionalization with nitroxide moieties, of polypropylene
glycol hydroxyl-terminated (PPG) using for the first time oxoammonium salts (Br-TEMPO) in the presence of Et3N in
solution under mild reaction conditions is discussed. As far we know the oxoammonium salts has not been used before
for this end in polymers. The functionalization process is carried out using only one synthetic pathway in where high
levels of functionalization (98%) measured by 1H-NMR and titration (as indirect test) were found. A functionalization
reaction mechanism is proposed, in where peroxides groups are formed. The structure of the difunctional
macroalkoxyamine containing peroxide bonds at the ends of each chain was confirmed by 1H-NMR. | |
