Cross-linked polyethylenes are being marketed by orthopaedic manufacturers to address the problem of osteolysis caused by polyethylene particulate wear debris. Wear testing of these cross-linked polyethylenes in hip simulators has shown dramatic reduction in wear rate compared with standard ultrahigh molecular weight polyethylene, either gamma irradiated in air or nitrogen - or ethylene oxide-s...

A method for calculating the size distribution of nanocrystalline elements polymer structure is proposed. The longitudinal (thickness) ultrahigh molecular weight polyethylene lamellae was calculated from calorimetric data. results maximum values are consistent with known data obtained by other methods. Keywords: heat capacity, effect, lamella, polyethylene.
