Abstract

An apparatus for the continuous modification of polymers in the flowable state by electron radiation, includes a device configured for converting polymers into the flowable state, a forming device and at least one irradiation device structured and arranged to provide electron radiation in a region of irradiation. Additionally, the apparatus includes at least one cooling device, a radiation guard and supply and discharge lines inside the radiation guard. The supply and discharge lines realize a continuous transport of the polymers in the flowable state at least through the radiation guard into the region of irradiation. Additionally, the supply and discharge lines realize a continuous transport of one of polymers remaining in the flowable state and modified at least inside the radiation guard and solid formed and modified polymers out of the region of the irradiation.
