The present invention relates to a ultra high molecular weight polyethylene molded article for artificial joints having molecular orientation of crystal orientation and to a method for preparing the same, wherein the polyethylene molded article having a low friction and excellent abrasion resistance is obtained by irradiating a low dose of a radioactive ray to the ultra high molecular weight polyethylene to introduce a small amount of crosslinking points within molecular chains, giving compression-deformation after melting at a high temperature around the melting point thereof, and cooling and solidifying.

Une pièce moulée en polyéthylène à poids moléculaire ultra élevée utile pour articulations artificielles présente une orientation cristalline ou moléculaire, un faible coefficient de friction et une excellente résistance à l'usure. Selon un procédé de production de cette pièce moulée, on irradie du polyéthylène à poids moléculaire ultra élevé avec une faible dose de rayonnements afin d'introduire des traces de points de réticulation croisée dans la chaîne moléculaire, on fait fondre le polymère à une température élevée proche de son point de fusion, on le déforme par compression avant de le refroidir pour de le solidifier.
