A flame-retardant cable includes at least one core having a conductor and at least one protecting layer surrounding the core. The protecting layer is made from a low smoke zero halogen (LS0H) flame-retardant polymer composition having at least 70 phr of a polyethylene homopolymer or copolymer having a density lower than 0.90 g/cmas a halogen-free polymeric base, 100 to 800 phr of at least one metal hydroxide, and at least 10 phr of a tannin.

The present invention relates to a polymer comprising repeating units consisting of a substituted pyrrole ring. In particular, the repeating units consist of substituted pyrrole containing polar groups capable of interacting with carbon allotropes such as carbon nanotubes, graphene or nanographites, in order to improve the chemical-physical characteristics of the allotropes mainly by increasing their dispersibility and stability in liquid media and in polymer matrices. The invention also relates to products of addition of these polymers with carbon allotropes in order to obtain easily dispersible macromolecules.
