Abstract: A flame-retardant cable includes at least one core comprising a conductor and at least one protecting layer surrounding the core. The protecting layer is made from a low smoke zero halogen (LSOH) flame-retardant polymer composition comprising at least 70 phr of a polyethylene homopolymer or copolymer having a density lower than 0.90 g/cm3 as a halogen-free polymeric base, and: a) 100 to 800 phr of at least one metal hydroxide; and b) at least 10 phr of a tannin.

Abstract: 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.
