TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The sulfonated polythiophene comprises a sulfonated regioregular polythiophene comprising alkyleneoxy and/or polyether. The aqueous dispersion comprises (wt.%) sulfonated polythiophene (0.1-8) and sulfonated regioregular polythiophene (0.1-8). The non-aqueous solvent comprises methyl-2-pyrrolidone (NMP), dimethyl sulfoxide (DMSO), dimethylformamide (DMF), tetrahydrofuran, 1-methoxy-2-propanol acetate, chloroform, a glycol and/or a glycol ether, preferably NMP, DMSO or DMF. The non-aqueous solvent is added to the aqueous dispersion at 80-120 wt.% of the aqueous dispersion. The sulfonated polythiophene is not associated with a doping polymer, and does not comprise polyethylenedioxythiophene or mixture of polyethylenedioxythiophene and polystyrene sulfonate. The sulfonated polythiophene comprises a sulfonated poly(3-(alkoxy)thiophene) or a sulfonated poly(3-(methoxyethoxyethoxy)thiophene). Preferred Method: The removal of water is done under reduced pressure at not greater than 100 mm mercury and/or by heating the mixture at greater than or equal to 40 degrees C; and heating at greater than or equal to 5 degrees C higher that temperature of the first heating to remove water from the mixture by greater than or equal to 80 (preferably greater than or equal to 90) wt.%. The method further comprising mixing mixture removed of water with a matrix polymer. The non-aqueous solvent is a polar, aprotic solvent; and mixing the sulfonated polythiophene with a hole transport material.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The matrix polymer is soluble in the non-aqueous solvent. EXAMPLE - A mixture of (g) 0.74 wt.% aqueous sulfonated poly(3-(methoxyethoxyethoxy)thiophene-2,5-diyl) (25) and anhydrous N-methyl-2-pyrrolidone (25) was added with solvent (25 g), evaporated under reduced pressure at 60 degrees C, added with anhydrous N-methyl-2-pyrrolidone (10 g), and evaporated under reduced pressure at 60 degrees C.
