“…The characteristic CAO stretching peak of carbonyl groups of PAA in curve III can be observed at the same wavenumber with a shoulder at 1620 cm Ϫ1 . In the case of PAA-PPy-Cu ternary complex, this main peak of PPy shifts to 1627 cm Ϫ1 because of the interaction of Py with carbonyl groups of PAA, which indicates the inclusion of PAA in precipi- tate as reported before 13 [ Fig. 7(b)].…”

“…In our report 13 the matrix polymerization reaction of Py in the PAA-Py-Ce(IV) ternary mixture was investigated by following the absorption of the soluble (homogenous) oxidized product. An example of such absorbance measurements is given in Figure 1, where three peaks were observed at three different wavelengths, i.e., 220 nm (I), 450 nm (II), and 850 nm (III).…”

“…The interaction of Ce(IV) ions with PAA was investigated in detail in our previous report 13 and the soluble and insoluble Me complexes were obtained by the titration of the PAA solution with Ce(IV). In this study, to eliminate the reason of precipitation in the PAA-PPy-Me ternary complex, the mole ratio of Me to PAA was chosen as 0.183 where the PAA-Me complexes were soluble and excess amount of Py was used to get both soluble and insoluble products.…”

“…The oxidative polymerization of Py in a polyacrylic acid (PAA) matrix by using Ce(IV) as an oxidant, which is known to be capable of polymerizing vinyl monomer 9 -11 and Py 12 efficiently, has been introduced recently. 13 The oxidative polymerization of Py in the presence of copolymers of vinyl pyrrolidone with acrylic acid also has been carried out.…”

The oxidative matrix polymerization of pyrrole (Py) by Fe(III), Cu(II), Ni(II), Co(II), and Zn(II) in the presence of polyacrylic acid (PAA) was studied and water‐soluble products along with insoluble products were obtained. The metal (Me) content of the insoluble part was determined by using atomic absorption spectroscopy (AAS). The effects of the oxidation potential of Me ions and ligands on the aggregation of polypyrrole (PPy) on the matrix polymer were measured by ultraviolet (UV)‐visible spectra. These findings also were checked by cyclic voltammetry (CV) measurements on PAA–Cu and PAA–PPy–Cu interactions. The conductometric titration results of PAA–PPy–Me ternary solutions were explained in the light of the interaction of Me ions with Py to polymerize on the PAA matrix resulting in some free carboxyl groups with a possibility of having Me–polymer complexes and a ternary complex (PAA–Me–PPy). The insoluble products were characterized by Fourier transform infrared (FTIR), elemental analysis, scanning electron microscopy (SEM), and four point probe conductivity measurements. © 1999 John Wiley & Sons, Inc.

The chemical oxidative polymerization of pyrrole (Py) by ceric ammonium nitrate (CAN) in the presence of polyitaconic acid and its copolymers (Polymer) containing 75 and 50 mole% N‐isopropylacrylamide were investigated. The effects of copolymer composition and addition order of the components on the reaction mechanism were studied by following the absorption spectra of the soluble reaction products between 200 and 1100 nm. As to the UV‐visible, FTIR and conductivity results of soluble products obtained from Polymer‐CAN‐Py system, it was assumed that the pyrrole polymerization by chemical oxidation was inhibited in the presence of the water‐soluble polyelectrolyte because an important part of ceric ammonium nitrate was consumed to produce radicals on the chains. On the other hand, the role of the copolymers in the case of Py‐CAN was mainly to prevent precipitation of polypyrrole. Consequently, the reaction prepared according to the first order of addition of the reactants favour the formation of oligomeric pyrrole, while the second order of addition yields solution of colloidal polypyrrole interacting with polyelectrolytes. © 1999 Society of Chemical Industry

Poly(N‐vinylcarbazole), poly(N‐carbazole) and poly(N‐ethylcarbazole) powders were chemically synthesized by the reaction of ceric ammonium nitrate (CAN) with N‐vinylcarbazole carbazole and N‐ethylcarbazole in acetonitrile. Products were characterized by elemental analysis, Fourier transform infrared spectroscopy, scanning electron microscopy and viscosity, X‐ray fluorescence and four‐probe conductivity measurement. It is found that when a suitable concentration of CAN is used in the polymerization process, the conductivity of chemically synthesized polymers can be improved further by controlling the CAN addition. © 1997 John Wiley & Sons, Ltd.
