Vinylaromatic polymer loaded with conductive carbon black

摘要

The invention concerns a composition comprising: 35 to 65 wt. % of radical vinylaromatic polymer, 5 to 40 wt. % of ethylene and alkyl(meth)acrylate copolymer, 2 to 20 wt. % of copolymer with vinylaromaticdiene monomer blocks, a necessary and sufficient amount of conductive black carbon for providing the composition with resistivity ranging between 1.104 to 1.109 omega.cm. The composition maintains good conductivity whatever the transformation mode used and has excellent impact resistance.
