NOVELTY - The device for continuous modification of polymers in fluid condition by electron radiation, comprises a device component for transforming the polymers into fluid condition, a radiation screen (2) for electron irradiation, and cooling mechanisms. An irradiation mechanism for electron radiation (6), inlet- and discharge lines (4) and shaping device (5) are present in the radiation screen. The device component is an extrusion or an interior mixer or synthesis reactor and is arranged exterior to the radiation screen.    USE - For continuous modification of polymers in fluid condition by electron radiation.    ADVANTAGE - The device is cost effective and irradiation takes place evenly in modification of the polymers.    DETAILED DESCRIPTION - The device for continuous modification of polymers in fluid condition by electron radiation, comprises a device component for transforming the polymers into fluid condition, a radiation screen (2) for electron irradiation, and cooling mechanisms. An irradiation mechanism for electron radiation (6), inlet- and discharge lines (4) and shaping device (5) are present in the radiation screen. The device component is an extrusion or interior mixer or synthesis reactor and is arranged exterior to the radiation screen. The radiation screen is composed of a material from elements with high atomic number, such as iron, lead, tungsten, or from concrete. The fluid polymers are present freely floating within the irradiation region after the shaping device. An irradiation device is arranged above, below and/or laterally to the irradiation region. Discharge and cooling devices are present within the radiation screen in which a radiation window is present above, below or adjacent to the irradiation region. Rollers are available as discharge and cooling devices. The devices for granulating, rolling, separation and/or transportation are present within or outside the radiation screen. Pipings are present for the transportation of the liquid polymers. The inlet- and discharge lines are heatable. A gear pump (3) is arranged after the device component for transformation of the polymers into the fluid condition. The arrangement of the openings in the radiation screen for the inlet- and discharge lines disallow a direct optical view of the irradiation region. The irradiation mechanism is an irradiation chamber within which the modification of the fluid polymers takes place. The irradiation chamber contains transportation and/or mixing devices and produces a melt profile of the fluid polymers in the irradiation chamber. The irradiation chamber exhibits a rectangular cross section and the fluid polymers within the irradiation region exhibit a foil-like form. The radiation screen with the inlet- and discharge lines is integrated into the continuous production process for polymers.    DESCRIPTION OF DRAWING(S) - The diagram shows a continuous production- and electrons irradiation process of melt foil:    Radiation screen; (2)    Gear pump; (3)    Inlet- and discharge lines; (4)    Shaping device; (5)    Electron radiation.
