Therefore, different structural features of these two dianhydrides and diamines significantly influence macromolecular conformation and physico-chemical properties of the synthesized polymers.

The diamines 9,9'-BAFL and 3,4'-diaminodiphenyl ether (3,4'-ODA) were used as received.
Both main components of mischmetall could potentially serve as highly coordinating metals for asymmetric diamine synthesis:
In this study, we synthesized PUFs from 4,4'-diphenylmethane diisocyanate (PMDI) and polypropylene glycols (PPG), which were prepared from four different types of initiators such as sorbitol and its combinations with toluene diamine (TDA), ethylene diamine (EDA), and sucrose/ glycerin.
For the polymerization the mole ratio of the two diamines was varied from 2/8 to 7/3 in increment of 10%.
But the direct condensation of simple diamines and simple diesters is addressed in only a few publications, all dealing with solutions, not with bulk systems [12-16].
The polycondensation of diamines and diesters stops early at the stage of oligoamides because it does not only yield the expected monoamide units BDA and, from those, the chain forming diamide units [B.
Quinone diimines are unlike phenylene diamines in their effects on vulcanization characteristics.
Promising modifiers for this purpose appeared to be polymeric amines and diamines based on poly(oxyalkylenes).
