摘要
PURPOSE:To obtain strong bonding by a method wherein a layer of polymer grains, granules or pellets is placed, a layer of ultrahighmolecular polyethylene grains or granules is provided on the above-said layer and is heated and pressed at the melting point or above of crystals of the ultrahighmolecular weight polyethylene. CONSTITUTION:A layer of polymer grains, granules or pellets is placed and on this layer is provided a layer of ultrahighmolecular weight polyethylene grains and granules and this layer is molded between the melting point of ultrahighmolecular weight polyethylene crystal and 300 deg.C, preferably at 150 deg.C min. and 250 deg.C max. and between 5kg/cm2 and 500kg/cm2 preferably at 10kg/cm2 min. and 250kg/cm2 max. In this manner, it is possible to obtain a polymer molded body that has a strong bonding on the boundary surface between the polymer and the ultrahighmolecular weight polyethylene and whose surface is coated with ultrahighmolecular weight polyethylene.
