THE PREPARATION OF ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE MORPHOLOGIES OF TOTALLY FUSED PARTICLES WITH SUPERIOR MECHANICAL PERFORMANCE.

摘要

semi crystalline structure to form high molecular weight polyethylene and its method of manufacture. the original stock or a stock powder partially merged and crystallized by fusion with a granular memory, is heated to a temperature at which the stock together to form a homogeneous melting completely loses the memory of the granular structure of the original stoco.the resultant casting is cooled to ambient temperatures under compression to provide a homogeneous, isotropic semi crystalline form.an anisotropic form high molecular weight polyethylene can be prepared by a solid-state deformation of semi crystalline form at a temperature close to its melting point but below the crystal, at a strain rate of about 5 to 8. the product is useful for the manufacture of the tendons.
