Thermoplastic composition comprising at least 40 % by weight and at the most 70 % by weight of a cross-linked polymer phase obtained by mixing at least one copolymer (a) comprising between 96 % and 55 % by weight of ethylene, between 3 and 30 % by weight of at least one alkyl or cycloalkylacrylate or methacrylate, of which the alkyl or cycloalkyl group has between 1 and 10 carbon atoms, and between 1 and 15 % by weight of at least one unsaturated epoxyde; of at least 1 copolymer (b) comprising between 84 and 55 % by weight of ethylene, between 15 and 39 % by weight of at least one alkyl or cycloalkylacrylate or methacrylate, of which the alkyl or cycloalkyl group has between 1 and 10 carbon atoms, and between 1 and 6 % by weight of at least one unsaturated dicarboxylic acid anhydride; and of at least one compound (c) capable of accelerating the reaction between the epoxy function present in the copolymer (a) and the anhydride function present in the copolymer (b); with at least 30 % by weight but at the most 60 % by weight of at least one saturated polyester. Application: production of moulded items. |
