Abstract

A mixture of inherently conductive polymer and plastisol is disclosed. Articles made from the mixture can be used as electrostatic dissipative (ESD) articles.

Claims (14)

1. A mixture, comprising:

inherently conductive polymer and graphite dispersed in a plastisol, wherein the plastisol is a liquid at room temperature of a dispersion of resin in a plasticizing liquid wherein the graphite comprised up to about 35 weight percent of the mixture and the inherently conductive polymer comprised from about 1 to about 50 weight percent of the mixture.

2. The mixture of claim 1 , wherein the plastisol contains polyvinyl chloride.

3. The mixture of claim 2 , wherein the inherently conductive polymer is a polyaniline.

4. The mixture of claim 1 , wherein the plastisol contains poly(methylmethacrylate).

5. The mixture of claim 1 , wherein the inherently conductive polymer is a polyaniline.

6. The mixture of claim 5 , wherein the inherently conductive polymer is lignosulfonic acid-grafted polyaniline.

7. A coating of a mixture, comprising inherently conductive polymer and graphite dispersed in a plastisol, wherein the plastisol is a liquid at room temperature of a dispersion of resin in a plasticizing liquid wherein the graphite comprised up to about 35 weight percent of the mixture and the inherently conductive polymer comprised from about 1 to about 50 weight percent of the mixture.

8. The coating of claim 7 , wherein the plastisol contains polyvinyl chloride.

9. The coating of claim 8 , wherein the inherently conductive polymer is a polyaniline.

10. The coating of claim 7 , wherein the plastisol contains poly(methylmethacrylate).

11. The coating of claim 10 , wherein the inherently conductive polymer is a polyaniline.

12. A molded article of a mixture, comprising inherently conductive polymer and graphite dispersed in a plastisol, wherein the plastisol is a liquid at room temperature of a dispersion of resin in a plasticizing liquid wherein the graphite comprised up to about 35 weight percent of the mixture and the inherently conductive polymer comprised from about 1 to about 50 weight percent of the mixture.

13. The article of claim 12 , wherein the plastisol contains polyvinyl chloride or poly(methylmethacrylate) and wherein the inherently conductive polymer is a polyaniline.
