A diamino-xanthene colorant is provided having the following structure: ##STR1## where Y is a poly(oxyalkylene) substituent having a straight or branched polymer chain of at least 3 monomer units selected from ethylene oxide, propylene oxide, butylene oxide and glycidol;

Poly(oxyalkylene) substituted xanthene colorant and method for making

A poly(oxyalkylene) substituted xanthene colorant is providing having the following structure: ##STR1## where Y is a poly(oxyalkylene) substituent having a straight or branched polymer chain of from 3 to 400 monomer units selected from ethylene oxide, propylene oxide, butylene oxide and glycidol;

Poly(oxyalkylene) substituted aminophenol intermediate and xanthene

A method is provided for the preparation of a conductive composition containing a polymerized aromatic amine wherein the aromatic amine is oxidatively polymerized in an acidic aqueous medium in the presence of an oxidizing agent, a doping agent and an aromatic polyalkyleneoxide in an amount sufficient to stabilize the resulting composition. Preferably, the aromatic amine is aniline or a substituted aniline. Compositions produced by such method are also disclosed. These compositions are useful for treating various substrates to make such substrates conductive.

Polyaniline dispersion and method for making same

A process for heat treating substituted and/or unsubstituted polyaniline which has been doped with a relatively non-volatile acid is provided. Subjecting polyaniline to temperatures of between 70.degree. C. and 200.degree. C. for a moderate amount of time dramatically lowers the resistance, and therefore increase the conductivity, of the polyaniline. Heat treatment of polyaniline may be advantageously combined with a subsequent rinsing step to produce a sample which has superior stability and good conductivity.

Method for enhancing polyaniline conductivity

Azo chromophores having polyoxyalkylene substituents are linked together by a covalent bond or by an intervening connecting group to form dimers or trimers. The polyoxyalkylene substituents are straight or branched chain polymers primarily of ethylene oxide which make the dimer and trimer colorants useful as fugitive tints.
