Method for producing polyaniline having self-doping function and antistatic agent containing polyaniline produced thereby

摘要

An aniline monomer having a phosphonic acid of general formula (4) is polymerized to produce a polyaniline. In the formula, R1 is NH2 or NH3X, and X is a halogen. R2 are each independently a phosphonic acid or a salt thereof. R3 are each independently selected from the group consisting of a halogen atom, alkyl group having 1-15 carbon atoms, aralkyl group having 7-34 carbon atoms, alkoxy group having 1-15 carbon atoms, alkylthio group having 1-15 carbon atoms, alkylamino group having 1-15 carbon atoms, carboxyl group, carboxylic acid alkyl ester group wherein the alkyl group has 1-15 carbon atoms, nitro group, and cyano group. m is an integer of 1-4, n is an integer of 0-3, and the sum of m and n is 1-4. However, none of R2 and R3 is present at the para position relative to R1.;

1. A method for producing a polyaniline, comprising a step of polymerizing an aniline monomer compound represented by the following general formula (4): (wherein R1 is NH2 or NH3X, and X is a halogen atom; R2 is each independently a substituent represented by the following general formula (5): M1 and M2 are each independently selected from the group consisting of a hydrogen atom, alkali metal, alkaline earth metal, ammonium group, and pyridinium group, with the proviso that when M1 or M2 is an alkaline earth metal, the structure is such that the alkaline earth metal atom is bound to two O− in one phosphonic acid group and M2 is not present, or such that the alkaline earth metal atom crosslinks O− of two phosphonic acid groups; R3 is each independently selected from the group consisting of a halogen atom, alkyl group in which the number of carbon atoms is 1 to 15, aralkyl group in which the number of carbon atoms is 7 to 34, alkoxy group in which the number of carbon atoms is 1 to 15, alkylthio group in which the number of carbon atoms is 1 to 15, alkylamino group in which the number of carbon atoms is 1 to 15, carboxyl group, carboxylic acid alkyl ester group in which the number of carbon atoms of the alkyl group is 1 to 15, nitro group and cyano group; m is an integer of 1 to 4; n is an integer of 0 to 3; and the sum of m and n is 1 to 4; with the proviso that neither R2 nor R3 is present at the para position relative to R1); or an aniline monomer mixture comprising the aniline monomer compound.
