WVP is monitored to determine the impact of grafted poly(IPA) and ionic carboxylate group on the water vapor permeation through PU membrane using the previous method [40, 41].
On the other hand, benzene multicarboxylate ligands play a significant role in the design and construction of coordination polymers [12-14] because of their fascinating characteristics including strong coordination ability, diverse coordination modes, various organic skeletons of carboxylate linkers, and extensive hydrogen-bonding interactions.
Some indole carboxylate compounds were detected internationally in patient samples, e.g., PB-22 (13, 14), 5F-PB-22 (15-17), and BB-22 (18).
Their optimal levels were determined by single-factor experiments using the change in the KBP properties, that is, crystallinity, viscosity, kappa number, and carboxylate content, as the response factors.
Both nitrogen atoms of amine groups are protonated, while the two carboxylic acid groups exist as carboxylate anions [6].
The IR spectrum displayed the typical asymmetric ([v.sub.asym]) and symmetric ([v.sub.sym]) carboxylate stretching frequencies at 1523 and 1455 [cm.sup.-1] ([DELTA] = 68 [cm.sup.-1]) and 1516 and 1454 ([DELTA] = 62 [cm.sup.-1]), respectively, for 1 and 2, confirming the presence of the quinoline carboxylate ligands coordinated in the chelating mode through the carboxylate to the metal center [23, 24].

The process includes masked irradiation of vacuum ultraviolet light on an amorphous perfluorinated polymer layer to photo-activate the surface with pendant carboxylate groups, and subsequent coating of alkylamine-encapsulated silver nanocolloids, which causes amine-carboxylate conversion to trigger the spontaneous formation of a self-fused solid silver layer.
