Abstract:
Methods of reducing the amount of undesirable by-products in the production of polymers are disclosed. The resulting polyetherimides have lower polydispersivity and enhanced thermomechanical properties. In some embodiments, cyclic and low molecular weight linear oligomers are also obtained.
