Abstract:
1. A flame-retarded flexible thermoplastic composition containing no halogen compound or phosphorous plasticizer, comprising a graft copolymer containing polyamide blocks and composed of a polyolefin backbone and on average at least one polyamide graft, in which the grafts are attached to the backbone by the radicals of an unsaturated monomer (X) having a function capable of reacting with an amine-terminal polyamide, the radicals of the unsaturated monomer (X) being fixed to the backbone by grafting or copolymerization from its double bond, wherein said composition comprises, in a mixture: 50% to 70% by weight of the graft copolymer containing polyamide blocks, 25% to 35% by weight of a flame retardant selected from ammonium phosphates, phosphinates, pyrophosphates, and polyphosphates, approximately 2% by weight of molecular sieve.
