Abstract: In crosslinking profies of C2H4 polymers having density 0.93-0.945 g/cc and melt index 1.5-10 g/10 min., the profiles are heated to 80-120 degrees C before passing under a source of radiation where they are irradiated with electron rays having energy 0.5-3 x 106 e.v. in dosage 50-300 kGy. Electrical charge in profile walls is prevented. Radiation yield is high. Heating increases degree of crosslinking achieved. The hot profiles are pref. quenched with water at 20 degrees C immediately after irradiation.
