Abstract
The present invention relates to a composition comprising polystyrene or modified-polystyrene or a mixture thereof, said polystyrene or modified-polystyrene or mixture thereof further comprising carbon nanotubes; wherein the composition comprises a polyolefin; and wherein the composition comprises at most 1.90% by weight of carbon nanotubes, based on the total weight of the composition. The present invention also relates to a method for the preparation of the composition, wherein the carbon nanotubes are provided in polyolefin or styrenic copolymer masterbatch.

1-13. (canceled)
A process for preparing a conductive composition comprising:
- (a) providing a masterbatch comprising at least 5% by weight of carbon nanotubes based on a total weight of the masterbatch, and a polyolefin and/or styrenic copolymer;
- (b) blending the masterbatch of step (a) with polystyrene, modified-polystyrene, or a mixture thereof, and with a polyolefin, in amounts such that the conductive composition is obtained, wherein the conductive composition comprises at most 1.90% by weight of carbon nanotubes, based on the total weight of the conductive composition.
