Chemical oxidative polymerization of dodecylbenzenesulfonic acid aniline salt in chloroform

Polymerizations of dodecylbenzenesulfonic acid aniline salt (DBSAn) in chloroform using various electron acceptors were studied as a function of polymer yield and conductivity. Dichlorodicyanobenzoquinone (DDQ) is an effective oxidant for the polymerization of DBSAn to yield sufficient amount of polyaniline. Suspension polymerization of DBSAn in chloroform with a small amount of water containing ammonium persulfate (APS) as an oxidant was found to yield a homogeneous transparent and green-black suspension containing polyaniline. Polyaniline was found to exhibit strong solvatochromism in aqueous and chloroform solutions.
