Title: The Innovations of Robert Scott Hensey
Introduction
Robert Scott Hensey is a notable inventor based in West Chicago, IL (US). He has made significant contributions to the field of polymer chemistry, particularly in the development of low molecular weight poly(1-olefins). With a total of 2 patents to his name, Hensey's work has implications for various industrial applications.
Latest Patents
Hensey's latest patents focus on reactive, low molecular weight, viscous poly(1-olefins). These patents describe catalysts and processes to create low molecular weight, essentially terminally-unsaturated, viscous poly(1-olefin) or copoly(1-olefin) with a high terminal vinylidine content. The process utilizes a Ziegler catalyst made from a Group IVb metallocene and an aluminoxane cocatalyst, particularly bis(cyclopentadienyl) and bis(indenyl) titanium(IV), zirconium(IV), or hafnium(IV) compounds along with methylaluminoxane. A particularly useful feedstock for this process is a refinery stream containing 1-olefins and isobutylene, which is essential for producing polyisobutylene. The resulting reactive poly(1-olefins) can be functionalized to create products useful as sealants, petroleum additives, and adhesives.
