The mechanical properties, the crystal orientation, and the microstructure of hot rolled and quench rolled ultrahigh molecular weight polyethylene (UHMW-PE) were investigated. The tensile strength of hot rolled and quench rolled UHMW-PE sheets increased with increasing draw ratio. The crystallograph

The roller drawing of ultrahigh molecular weight polyethylene (UHMW-PE) sheets were carried out in the roller temperature T, range of 100-140ยฐC. In addition to the roller drawing in the solid state (T, = lOOT), we attempted to crystallize the molten UHMW-PE sheet under the rollerdrawing process (T,
The drawing behavior of the ultra-high molecular weight polyethylene (UHMW-PE) melts has been studied by comparing the stress/strain curves for two types of samples as polymerized using conventional Ziegler and newer metallocene catalyst systems. Two UHMW-PE samples, having the same viscosity averag
The extent of recrystallization of nascent UHMWPE powder is easily measured by calorimetry. Melting and recrystallization of nascent UHMWPE at 140ยฐC can be suppressed by compression molding. Crystals of UHMWPE prepared from dilute solution show a peak melting temperature of 140ยฐC and exhibit crystal
