Abstract
Esterification of soluble polymers by direct condensation of equimolar amounts of carboxylic acids with polyethylene glycols is achieved using catalytic Sc(OTf)3 in toluene for the first time. The first esterification of a soluble polymer by condensation of equimolar amounts of carboxylic acids and polyethylene glycols is achieved using catalytic Sc(OTf)3 in toluene.
