Summary
Hot drawing of high molecular weight polyethylene (\(\left( {\bar M_w = 1.5 \times 10^6 } \right)\)) was studied. It was found that solutioncast films exhibited a drastically increased drawability in comparison with melt-crystallized material. This phenomenon, which enabled the production of polyethylene structures with a Young's modulus of 108 GPa and a strength of 3.0 GPa, is discussed in terms of a reduced number of entanglements in solution-crystallized material related to melt-crystallized films.
