Abstract
The protonation of several poly(amido-amines) and their non-macromolecular model compounds has been studied in aqueous solution by 13C n.m.r., potentiometric, and calorimetric techniques. Sharp basicity constants and thermodynamic functions have been obtained with poly(amido-amines), thus confirming the peculiar behaviour of this family of polymeric bases. The behaviour of the models is similar to that of the corresponding polymers. However, they are constantly slightly more basic. This difference is mainly due to the entropy term.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
