The molecular weight distribution of some low‐pressure homopolymers of ethylene intended for use in blown bottles have been determined by using a modified sand column technique. A correlation is indicated between the Z ‐average molecular weight M̄ z and the postextrusion swelling of the resin as measured by the weight of a bottle blown from that polymer.
