Latest Patents

Nygard's latest patents include a novel polyethylene process that discloses an ethylene polymerization method. This process involves polymerizing ethylene in two slurry reaction zones with a C-Calpha-olefin, utilizing a single-site catalyst. The result is a high molecular weight polyolefin that yields medium density and linear low density polyethylene. This polyethylene exhibits a bimodal molecular weight distribution and a melt index ranging from about 0.10 to about 0.80. The films produced from this polyethylene showcase superior impact properties. Another significant patent involves the preparation of polyethylene thin films. This process entails extruding a blend of linear low density polyethylene (LLDPE) and either high molecular weight, high density polyethylene (HMW-HDPE) or high molecular weight, medium density polyethylene (HMW-MDPE). The blend is extruded through an annular die to form a molten material tube, which is then processed to create films with increased machine-direction tears.
