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.;
