Ultra high molecular weight polyethylene articles and methods of forming ultra high molecular weight polyethylene articles

Abt and Schneider-Storrer of Zimmer, Switzerland, formed implantable articles from a crosslinked ultrahigh molecular weight polyethylene ("UHMWPE") blend stabilized with Vitamin E. The crosslinked UHMWPE blend may be prepared by combining the UHMWPE material and vitamin E prior to irradiating the UHMWPE blend with electron beam radiation at a sufficient radiation dose rate to induce crosslinking. The crosslinked UHMWPE blend may be incorporated into a variety of implants, and in particular, into endoprosthetic joint replacements.  (RDC 5/11/2011)

Modular polymeric projectile absorbing armor

Duke and Barrett of Ballistics Blocks, Georgia have developed an anti-ballistic structure consisting of interlocking blocks of laminates of linear low density polyethylene and thermoset such as elastomeric polyurethanes or EPDM.  (RDC 5/9/2011)

7,838,611
Ethylene polymer, catalyst for ethylene polymer production, and method for producing ethylene polymer

7,837,950
Apparatus for the production of polyethylene and ethylene copolymers

Van Nuland et al of ExxonMobil, Texas, developed an apparatus and a process for the high pressure polymerization of ethylene, optionally with one or more comonomers, in which unreacted monomer is separated from the polymer in a separation system in separation vessels and is recombined back into the product mixture upstream of the first separation vessel, preferably using a jet pump.  (RDC 4/8/2011)
