Patent ID: 7204940

Claim:
A conductive composition comprising: (A) a crosslinked polymeric material formed by a process comprising reacting a polymer and a crosslinking agent, wherein the polymer has side chains along a backbone forming the polymer, at least two of the side chains being substituted with one or more heteroatoms selected from the group consisting of oxygen, nitrogen, sulfur, phosphorus and combinations thereof, the polymer formed by reacting a mixture comprising (i) one or more monomers selected from the group consisting of unsaturated dicarboxylic acids, esters of unsaturated dicarboxylic acids, anhydrides of unsaturated dicarboxylic acids, and mixtures thereof; and (ii) one or more amines selected from the group consisting of R—NH 2 , a polyalkylene polyamine, and mixtures thereof, wherein the R group contains between 1 and 50 carbon atoms and one or more of the selected amines includes at least two amino groups; and (B) a plurality of copper species distributed within the crosslinked polymeric material, wherein the conductive composition has a resistance of no more than about 100 ohms.
