Title: Innovations by Joel D. Wieliczko
Introduction
Joel D. Wieliczko is an accomplished inventor based in Channahon, IL (US). He has made significant contributions to the field of polymer science, particularly in the development of polyethylene formulations and copolymers. With a total of 2 patents, his work has had a notable impact on manufacturing processes.
Latest Patents
Wieliczko's latest patents include innovative formulations for large part blow molding applications. One of his notable inventions involves a polyethylene formulation characterized by a density greater than 0.940 g/cm³, measured according to ASTM D792. This formulation also features a high load melt index ranging from 1.0 g/10 min to 10.0 g/10 min, measured at 190°C with a 21.6 kg load. Additionally, the formulation has a peak molecular weight of less than 50,000 g/mol and a number average molecular weight of less than 30,000 g/mol. The weight fraction of molecular weight less than 10,000 g/mol is less than or equal to 10.5 wt %, as determined by Gel Permeation Chromatography (GPC). Articles produced from this polyethylene formulation, particularly those made through blow molding processes, demonstrate enhanced performance.
Another significant patent by Wieliczko is related to an antifoulant for impact copolymers. This process involves introducing an antifoulant to a second polymerization reactor that operates in series with a first reactor. The antifoulant can be a multicomponent antifoulant and/or a coating agent, which helps inhibit reactor fouling during polymerization. This innovation enables the production of a heterophasic copolymer with an Fc value ranging from about 10% to about 50%.
