Latest Patents

One of David's latest patents involves a novel processing method for olefin copolymers. This invention is directed to essentially saturated hydrocarbon polymer compositions that include a backbone chain and a plurality of hydrocarbyl sidechains. These sidechains have a number-average molecular weight ranging from 2500 Daltons to 125,000 Daltons, with a molecular weight distribution (MWD) by size exclusion chromatography (SEC) of 1.0-3.5. The invention also specifies that the Newtonian limiting viscosity at 190°C is at least 50% greater than that of a linear olefinic polymer of the same chemical composition and weight average molecular weight. Furthermore, it outlines specific ratios for the rubbery plateau modulus and extensional viscosity, demonstrating improved processing characteristics such as shear thinning behavior and strain thickening.
