Abstract
Thermoplastic composition comprising at least 40% by weight and not more than 70% by weight of a crosslinked polymer phase obtained by blending at least one copolymer (a) of 96 to 55% by weight of ethylene, of 3 to 30% by weight of at least one alkyl or cycloalkyl acrylate or methacrylate in which the alkyl or cycloalkyl group contains from 1 to 10 carbon atoms, and of 1 to 15% by weight of at least one unsaturated epoxide, at least one copolymer (b) comprising from 84 to 55% of ethylene by weight, from 15 to 39% by weight of at least one alkyle or cycloalkyl acrylate or methacrylate in which the alkyl or cycloalkyl group contains from 1 to 10 carbon atoms, and from 1 to 6% by weight of at least one arthydride of an unsaturated dicarboxylic acid, and at least one compound (c) capable of accelerating the reaction between the epoxy functional group present in the copolymer (a) and the arthydride functional group present in the copolymer (b); with at least 30% by weight but not more than 60% by weight of at least one saturated polyester.
