Latest Patents
Seungwoo Choi holds a patent for a "Polyethylene pipe having better melt processibility and high resistance to stress and method of preparing the same using metallocene catalyst." This invention provides an ethylene-based copolymer designed for non-crosslinked water supply pipes. The copolymer is prepared using a supported hybrid metallocene catalyst and features a dimodal or broad molecular weight distribution. It possesses a high-density molecular structure at low molecular weight and a low-density structure with a high comonomer content at high molecular weight. The molecular weight distribution ranges from 5 to 30, with copolymerization of ethylene and α-olefin localized in high molecular weight chains. This innovative copolymer exhibits superior processability, internal pressure creep resistance at elevated temperatures, and environmental stress crack resistance.
