Title: Timothy D. Van Domelen: Polymer Process Inventor
Introduction
Timothy D. Van Domelen is an inventor associated with Amherst, New York, and E. I. du Pont de Nemours and Company. His patent work includes a process for preparing poly(tetramethylene ether) glycol, a polymer used in industrial applications.
Latest Patents
Van Domelen is credited with 2 patents. The supplied patent information lists “Process for Preparing Poly(tetramethylene Ether) Glycol” twice, with the same description. The invention concerns polymerizing tetrahydrofuran using fluosulfonic acid as a catalyst. It describes how limiting iron sulfites in the acid to no more than about 1,200 parts per million can significantly reduce the color level of the resulting polymer.
Career Highlights
Van Domelen’s listed patent work reflects an interest in improving polymer production and product quality. The described process focuses on controlling catalyst impurities to achieve a lower-color poly(tetramethylene ether) glycol.
Collaborations
His listed coworkers include William W. Kasper and Willard L. Quon. The available information identifies these professional associations but does not specify their individual roles in the patent work.
Conclusion
Timothy D. Van Domelen’s recorded invention addresses a practical challenge in polymer manufacturing by linking catalyst purity with the color quality of the resulting material.
