Abstract
The extensional viscosity of a styrenic resin is enhanced by increasing the Z+1 average molecular weight (Mz+1) of the resin. In one embodiment, an enhanced extensional viscosity resin is provided that has an Mz+1 molecular weight of at least approximately 745,000 and an extensional viscosity having a minimum value of approximately 360,000 Pascal-seconds (Pa-sec).
