E. Schab-balcerzak et D. Sek, New soluble polyimides containing hydroxylic groups: I. Synthesis and characterization, HIGH PERF P, 13(1), 2001, pp. 45-53
A series of aromatic polyimides from different diamidedianhydrides and 2,4-
diaminophenol dihydrochloride was synthesized using a one-step high-tempera
ture polycondensation. The structural characterization of the prepared poly
imides was carried out by using Fourier transform infrared spectroscopy and
H-1 nuclear magnetic resonance spectroscopy. The influence of the monomers
' structures on the polymers' properties has been investigated.
