COMPOSIÇÃO DE POLÍMERO QUE COMPREENDE NANOTUBOS DE CARBONO. A presente invenção refere-se a uma composição compreendendo poliestireno ou poliestireno modificado ou uma mistura destes, o dito ou poliestireno modificado com poliestireno ou uma mistura destes, que compreende ainda os nanotubos de carbono; em que a composição compreende uma poliolefina; e em que a composição compreende mais de 1,90% em peso de nanotubos de carbono, com base no peso total da composição. A presente invenção também se refere a um método para a preparação da composição. A composition can include polystyrene, modified-polystyrene, or a mixture thereof. The polystyrene, modified-polystyrene, or mixture thereof can include carbon nanotubes. The composition can also include a polyolefin. The composition can include at most 1.90% by weight of carbon nanotubes, based on a total weight of the composition. The composition can be prepared by providing a masterbatch including at least 5% by weight of carbon nanotubes based on a total weight of the masterbatch, and a polyolefin and/or styrenic copolymer. The masterbatch can be blended with polystyrene, modified-polystyrene, or a mixture thereof, and with a polyolefin, in amounts such that a conductive composition is obtained. An article can be made of the conductive composition.
