  • Patent number: 4148956
    Abstract: Thermoplastic moulding compositions of linear polyesters and styrene/acrylonitrile modified by .alpha.-methylstyrene and/or acrylates can readily be processed to give mouldings which have outstanding toughness characteristics and other mechanical properties. Furthermore, from these moulding compositions it is possible to produce sheets which can be hot-laminated without patterns applied thereto being destroyed.
