A new chemical polymerization process for substituted anilines

Benzoyl‐Peroxide‐Initiated Inverse Emulsion Copolymerization of Aniline and o‐Toluidine: Effect of Dodecylbenzenesulfonic Acid on the Physicochemical Properties of the Copolymers

“…The vibrational frequencies of the major IR bands and their assignments are summarized in Table 5. [11,[26][27][28] In general, with some exceptions, the spectral characteristics of the copolymers show greater similarity to the IR spectrum of POT. [4] The band at 1 461 cm À1 of PANI attributed to the aromatic ring C-C stretching mode is blue shifted to 1 484 cm À1 for POT, whereas this mode for copolymers appears in the range of 1 478-1 486 cm À1 .…”

“…The -CH out-of-plane bending mode characteristic of 1,2,4-trisubstituted aromatic ring of POT appears as two strong bands at 882 and 828 cm À1 , whereas, in case of PANI (1,4-disubstituted benzene ring), it appears as a strong band at 787 cm À1 . [27] In case of the copolymers, bending modes characteristic of both tri-and disubstituted rings S. Shreepathi, R. Holze Table 5. Major IR bands and their assignments for PANI, POT and poly(aniline-co-o-toluidine)s.…”

“…[11,[26][27][28] cm S1 are present. The intensity of the bands due to trisubstituted rings increases and disubstituted rings decreases as the mole fraction of o-toluidine in the feed is increased and vice versa.…”

Polymerization of Aniline through Simultaneous Chemical and Electrochemical Routes

“…4 There is a considerable attention to polyaniline and has been widely investigated for electronic and optical applications due to its good environmental stability and tunable electrical and optical properties. 12,13 Polymerization of the monomer aniline, can be achieved either chemically [14][15][16][17][18][19][20][21][22][23][24][25] or electrochemically. [26][27][28][29][30][31][32][33][34][35][36] In fact, both polymerization routes have been widely investigated in the literature.…”

Preparation of poly(2‐anilinoethanol) containing azobenzene group under electrical field and its liquid crystalline properties investigation

“…PANI films can thus be spin-coated in the conducting form onto substrates. [2] Liquid-crystalline polymers, LCPs, are of increasing interest because of the favorable combination of key properties such as strength, easy flow, excellent dimensional stability, ability to incorporate high levels of fillers, excellent chemical resistance and remarkably low gas permeability. [3] Moreover, a wide range of properties can be obtained in LCPs with simple chemical variations in their structure, so that these materials are very good models to investigate the influence of such variations on the final properties.…”
