Ultra-high molecular weight polyethylene (UHMWPE) has become the gold standard for total joint replacements such as tibial inserts because of its chemical inertness, superior mechanical properties, and biocompatibility. Ethylene oxide sterilization is one most common effective methods used, especially polyethylene-based polymeric implants. However, variable conditions can cause a change in stru...

Bimodal polyethylene is generated from a single immobilized catalyst on support under set of reaction conditions without introducing chain transfer agents. Using rac-ethylenebis(1-indenyl)zirconium dichloride [(EBI)ZrCl2] nickel-containing layered double hydroxide (LDH) produces two distinct molecular weight distributions. The ratio these fractions can be tuned by varying the LDH as well changi...
