In spite of processing difficulties, some higher-molecular-weight polymers, such as ultrahigh-molecular-weight polyethylene (uhmwpe), are used because of their superior toughness. 

As shown in Table 12.1 the impact resistance and tensile strength of ultrahigh-molccular-weight polyethylene (uhmwpe) are superior to those of hope, but uhmwpe is more difficult to process, uhmwpe is also slightly harder than hdpe.

Polymers of MMA, AAc, and MAA were grafted onto an ultrahigh molecular weight polyethylene (UHMWPE) fiber surface after pretreatment with electron beam irradiation [31]. Sundell et al. [32] pretreated a PE film with electron beams to facilitate the graft polymerization of vinyl benzylchloride onto the substrate. The inner surface of porous PE hollow fiber had also been modified by grafting of glycidyl methacrylate (GMA) polymer after electron beam irradiation [33]. 

Ultra-high molecular weight polyethylene (UHMWPE) has been used in orthopaedic prosthetic surgery for many years due to its excellent mechanical properties and frictional resistance. A large number of studies on both retrieved prostheses and raw material have, however, been necessary in order to understand and prevent degradation of the prostheses. The shape of the prostheses and the compression moulded blocks from which they are cut is usually not suitable for examination. In a number of studies microtomy has therefore been used in order to produce pieces suitable for further studies [112, 113, 114, 115, 116, 117, 118, 119, 120]. However, very often when microtomy is used, it is without any consideration of the fact that the process... 

Ultrahigh molecular weight polyethylene (UHMWPE) is an engineering plastic which has a wide spectrum of applications, particularly as a material for orthopedic prostheses due to its high strength, high resistance to chemicals and physical abrasion, high wear...

Greatest drawability was studied for blend films with branched low molecular weight polyethylene (B-LMWPE) and ultra-high molecular weight polyethylene (UHMWPE) prepared by gelation/crystallization from solutions. The morphology of B-LMWPE-UHMWPE dry gel film was determined by solid-...
