The decrease ratio of the peak corresponding to the imide bonds was used based on the peak intensity corresponding to the C-F bond because the bond number of C-F did not change before and after the reaction.
The imide content is calculated from the ratio of imide-related bands (1765 [cm.
The FT-IR spectra of copolymer CNPAM is shown absorption band of the C = C of imide ring at 948[cm.
When SMA imide resins were used as coagulants with chemical recycled pulp and TMP, the retention of fines and fillers was measured to be high.
During the thermal cyclization from co-PAA to co-PI, the isoimide and intermolecular links can be formed due to the side reactions depending upon the reaction conditions and the type of imide molecules being heat-treated .

The characteristic bands for imide rings at 1775, 1716, 1380, and 742 [cm.
which we are proposing is the formation of an imide
One is that the gap of the backbone and side chain should be small enough to make it possible for electric interaction to take place, namely, having enough draw ratios, the other is that the trail phenyl of side chain should be close to carbonyls in imide rings of backbone since electric interactions only take place in small steric area.
