The production of high impact strength molding compositions obtained by thermal treatment of synthetic resin mixtures containing predominantly polyalkylene terephthalate, in the solid form, characterized in that the synthetic resin mixture contains A. 70-95% or 60-97% by weight of polyalkylene terephthalate and B. when A is 70-95%, 5-30% by weight of a conventional, elasticizing acrylate graft copolymer, a conventional alpha -olefin copolymer or a conventional polyether amide, or when A is 60-97%, 3-40% of a conventional polyether ester amide, and that the synthetic resin mixture is treated at temperatures of 15 DEG -60 DEG C. below the melting point of the pure component A in an inert gas atmosphere. |
