摘要

Flame-retarded polymer compositions comprising a hydrated inorganic filler, at least one ethylene/alkyl (meth)acrylate copolymer and at least one copolymer of ethylene and of at least one alpha -olefin, which compositions consist essentially of 120 to 240 parts by weight of hydrated inorganic filler per 100 parts by weight of a polymer phase consisting of: (a) 30 to 75 parts by weight of at least one ethylene/alkyl (meth)acrylate copolymer (A) having a content of alkyl (meth)acrylate of between 1 and 50 mol %, (b) 10 to 30 parts by weight of at least one ethylene/alkyl (meth)acrylate/unsaturated dicarboxylic acid anhydride terpolymer (B), (c) 5 to 55 parts by weight of at least one copolymer of ethylene and of at least one alpha -olefin (C) having a density of between 0.865 and 0.915 and a degree of crystallinity equal to at least 5%, and (d) 0 to 5 parts by weight of at least one low-density polyethylene (D). Industrial articles comprising such a flame-retarded polymer composition.
