Thermoplastic composition comprising not less than 60 % by weight of a saturated polyester and not more than 40 % by weight of at least one polymer reinforcing agent. Said polymer reinforcing agent is an at least partially cross-linked composition obtained by mixing: (a) at least copolymer comprising 94 to 60 % by weight of ethylene, 5 to 25 % by weight of at least one alkyl or cycloalkyl acrylate or methacrylate, the alkyl or cycloalkyl group of which has 2 to 10 carbon atoms, and 1 to 15 % by weight of at least one unsaturated epoxyde, (b) at least one copolymer comprising 84 to 60 % by weight for ethylene, 15 to 34 % by weight of at least one alkyl or cycloalkyl acrylate or methacrylate, the akyl or cycloalkyl group of which has 2 to 10 carbon atoms, and 1 to 6 % by weight of at least one unsaturated dicarboxylic acid anhydride, and (c) at least one compound capable of accelerating reaction between the epoxy function present in the copolymer (a) and the anhydride function present in copolymer (b). Application to the production of moulded articles. |
