End Groups in Condensation Polymers

Another important area of polymer chemistry for which end group analysis is often sought is in the polyester industry. This section will attempt to describe 

Several techniques for determination of end group structure in polyesters have been described in the literature [25-31]. Many analytical procedures have 

A simple conversion for PET gives (in the case of acid ends)  

One of the issues in using solution state NMR for PET analysis is that, due to the high crystallinity content of the polymer, it is fairly difficult to dissolve. Harsh
