The imidization synthesis involves the formation of imide rings, followed by the depletion of the amides groups (Fig.
In this reaction we were able to form both substituted and unsubstituted cyclic imides through two condensation reactions of the cyclic anhydride and the glutamic acid moieties, respectively.
Imide containing glycidylether (PPGE) and phosphorous containing amine were successfully synthesized and analyzed.
The imide content is calculated from the ratio of imide-related bands (1765 [cm.sup.-1]) to styrene-related bands (1602 [cm.sup.-1]), after calibration with a fully imidizcd sample (obtained after drying the dispersion at 200[degrees]C).
The FT-IR spectra of copolymer CNPAM is shown absorption band of the C = C of imide ring at 948[cm.sup.-1] and vinyl group at 990 [cm.sup.-1] of MMA are disappeared completely.
Overall, SMA imide resins are versatile chemicals with intrinsic properties that can be used under diverse conditions.
Nucleophilic attack of the primary amine to the carbonyl group of the imide ring occurred (Fig.
All the fibers exhibit four typical characteristic absorption bands: 1774[ cm.sup.-1] (C=0 of cyclic imide asymmetric stretching), 1714 [cm.sup.-1] (C=0 of cyclic imide symmetric stretching), 1354 [cm.sup.-1] (C--N--C axial stretching) and 738 [cm.sup.-1] (imide ring vibration), indicating the successful formation of the cyclic imide rings.
It helps us to monitor the decomposition (relationship between amide/imide bonds) and the orientation (relationship between imide bonds) after corona aging.
As shown in figure 2, this creates a conjugated system via the two aromatic rings, known as a quinone imide. Although this oxidation has a minimal effect on the physical properties of a TPU, this leads to irreversible yellowing of the TPU.
To over-overcome these drawbacks, modifications of the polyimide structure are often used, for example, introducing flexible linkages, nonsymmetrical structures, or bulky substituents into the polymer backbones (3-5) Aromatic poly(amide imide)s have been developed as alternative materials offering a compromise between excellent thermal stability and processability.
