    Abstract: The present invention relates to a composition that comprises a mixture of polymers, which comprises: a first polymer comprising polyphenylene sulphide, making up 55 wt % to 95 wt % of the mixture; a thermoplastic modifier, making up 5 wt % to 45 wt % of the mixture; optionally one or more functional additives, making up at most 10 wt % of the mixture, preferably at most 5 wt % of the mixture, characterised in that the thermoplastic modifier includes a second polymer which comprises a polyolefin backbone containing a group of at least one unsaturated monomer (X) and a plurality of polyamide grafts. The invention also relates to a multilayer structure including a plurality of adjacent layers, at least one of which consists of the aforementioned composition.
