1. A fluid-phase processible electrically conductive polymeric composition comprising an admixture of:

  • (a) at least one electrically conductive polymer selected from the group consisting of electrically conducting optionally substituted protonated polyaniline, and a copolymer thereof;

    (b) at least one aromatic compound selected from the group consisting of substituted aromatic compounds of Formulas (IV) to (X) ##STR15## wherein;

    each R1 represents H, --OH, --F, --Cl, --CH3 or --OCH3, wherein one or more of the hydrogen atoms in the --CH3 or --OCH3 groups may be substituted by --F or --Cl;

    each R2 is independently selected from the group consisting of --H, --OH, alkyl, alkenyl, alkoxy, alkanoyl, alkylthio, alkylthioalkyl, alkyl amide, alkylamidealkyl, alkyl hydroxy, alkyl carboxyl, having from 1 to about 20 carbon atoms;

    alkylaryl, arylalkyl, alkylsulfinyl, alkoxyalkyl, alkylsulfonyl, alkoxycarbonyl, wherein the alkyl or alkoxy moiety has from 0 to about 20 carbon atoms;

    or any two R2 groups together may form an alkylene or alkenylene chain completing a 3 to 7-membered aromatic or alicyclic ring, which ring may optionally include one or more nitrogen, sulfur or oxygen heteroatoms;

    each Y1 is independently selected from the group consisting of --OH, --COOH, --COO--Z, --CO--Z, --SO--Z, --SO2 --Z, SO2 NH--Z and --OCOO--Z, wherein Z represents an alkyl having 1 to about 20 carbon atoms;

    each Y2 is --OH;

    each W1 is independently selected from the group consisting of substituents of formulas X1, --C(Cn H2n+1) (Cm H2m+1)--X1, wherein n and m are integers from 1 to about 20, --COO--X1, --CO--X1, --OCO--X1, --CH2 --O--X1, --O--CH2 --X1, --O--X1, --S--X1, --SO--X2, --SO2 --X1, --SO2 NH--X1, --OCOO--X1, cyclohexyl, and 5 or 6 -membered aromatic, heteroalicyclic, heteroaromatic or alicyclic carbon rings;

    each W2 is independently selected from the group consisting of substituents of formulas X1, --C(Cn H2n+1) (Cm H2m+1)--X1, wherein n and m are integers from 1 to about 20, --COO--X1, --CO--X1, --OCO--X1, --O--X1, --S--X1, --SO--X1, --SO2 --X1, --SO2 NH--X1, --OCOO--X1, --COO--CH2 --X1, --OCO--CH2 --X1, --CH2 --COO--X1, --CH2 --OCO--X1, --O--C2 H4 --O--X1, cyclohexyl, and 5 or 6-membered aromatic, heteroalicyclic, heteroaromatic or alicyclic carbon rings andeach W3 is independently selected from the group consisting of substituents of formulas X1, --C(Cn H2n+1) (Cm H2m+1)--X1, wherein n and m are integers from 1 to about 20, --COO--X1, --CO--X1, --OCO--X1, --O--X1, --S--X1, --SO--X1, --SO2 --X1, --OCOO--X1, --CH2 --X1, cyclohexyl, and 5 or 6-membered aromatic, heteroalicyclic, heteroaromatic or alicyclic carbon ring; and

    each X1 is a group of formula (X) ##STR16## wherein R1 and R2 are as defined above; and

    (c) at least one surface active additive, wherein said substituted aromatic compound together with said surface active additive is capable of dissolving said electrically conductive polymer during processing.
