Chain mobility in polymer systems between solid and melt:sintering via the mobile hexagonal phase

摘要

UHMW-PE possesses excellent mechanical properties notably a high abrasion resistance and excellent wear and friction characteristic which makes is suitable for high demanding applications like in hip and knee prosthesis.The problem that arises from the high molecular weight is high melt viscosity,which makes the material intractable via conventional routes encountered in processing of thermoplasts.
