Abstract

Polyphenylene sulphide-based compositions with high impact strength essentially comprising, by weight, 60 to 99.5 parts of polyphenylene sulphide and 0.5 to 40 parts of a combination C comprising at least one compound Cl chosen form olefinic elastomers comprising epoxy groups and at least one tertiary amine C2. During the preparation of these compositions, the tertiary amine C2 is preferably incorporated in last place with respect to the other constituents.
