Abstract (en)
[origin: WO9842453A1] The method of irradiating polymer films by an electron beam comprises a two-stage application of an accelerated electron beam on sections of moving polymer film until the preset radiation dose has been absorbed. The duration of the set time interval between the end of treatment Stage one and the beginning of treatment Stage two of the initially irradiated film is not less than 500 msec. The set dose accumulated by each section of the film in Stage one is sufficient to alter the polymer film material from a free molecular state to a cross-linked state characterized by the formation of 3-dimensional molecular structures having a greater molecular mass.
