## Abstract Poly(ethylene glycol)s, with different molecular weights (4,000β20,000) and a monomethoxyβsubstituted poly(ethylene glyco) (molecular weight 5,000) have been quantitatively end group functionalized with bromo and amino groups. The bromination was carried out with thionyl bromide in tolu
