THE PREPARATION OF ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE MORPHOLOGIES OF TOTALLY FUSED PARTICLES WITH SUPERIOR MECHANICAL PERFORMANCE |
摘要 |
<p>An isotropic semicrystalline morphology of ultra-high-molecular-weight polyethylene and a method of making it. An original powder stock or a partially fused, melt-crystallized stock having a granular memory, is heated to a temperature at which the stock fuses completely to form a homogeneous melt which loses memory of the granular structure of the original stock. The resultant melt is cooled to ambient temperatures under compression to provide a novel homogeneous isotropic semicrystalline morphology. An anisotropic morphology of ultra-high-molecular-weight polyethylene may then be made by solid-state deforming that semicrystalline morphology at a temperature near but below its crystalline melting point at a deformation ratio of about 5 to 8.</p> |
