Abstract: A METHOD OF AFTER-TREATING HIGH-PRESSURE POLYETHYLENE IN SHEARING UNIT, WHEREIN THE HIGH-PRESSURE POLYETHYLENE IS INTRODUCED INTO THE SHEARING UNIT AT 200* TO 300*C. AND A VISCOSITY OF 5X10**3 TO 1X10**5 POISES AND SUBJECTED TO A SHEARING GRADIENT, THE SHEARING SURFACES CONTACTING THE POLYETHYLENE MELT BEING HEATED A TEMPERATURE WHICH IS AT LEAST AS HIGH AS THAT OF THE POLYETHYLENE MELT AND THE POLYETHYLENE MELT BEING SHEARED AT SUCH A SHEARING SPEED THAT THE PRODUCT OF SHEARING SPEED AND RESIDENCE TIME IN THE SHEARING ZONE IS EQUAL TO 5X10**2 TO 5X10**4.
