Title: Innovations of David G. Ward in Polymerization Processes

Introduction

David G. Ward is a notable inventor based in Geismar, Louisiana, recognized for his contributions to the field of polymer chemistry. He holds two patents that focus on advanced processes for the polymerization and copolymerization of alpha olefins. His work has significant implications for the production of poly alpha olefins, which are widely used in various industrial applications.

Latest Patents

Ward's latest patents include a process for the polymerization or copolymerization of an alpha olefin. This innovative solution process involves adding a Lewis acid to an alkyl aluminum in a hexane or heptane to form a coordination complex. The process requires continuous stirring to create a near-homogeneous solution in an inert anhydrous environment. Subsequently, at least one dry metallocene is added to this solution, forming a soluble polymerization initiator. The polymerization of an alpha olefin is then carried out using this enriched initiator, with the option to add additional alkyl aluminum as a moisture or impurities scavenger to yield a poly alpha olefin.

Another significant patent by Ward is a homogeneous polymerization catalyst system for the polymerization or copolymerization of alpha olefins. This system comprises a Lewis acid, an alkyl aluminum in hexane or heptane, and at least one dry metallocene, which contains a transition metal compound. The catalyst system is designed to produce poly alpha olefins from alpha olefin monomers or mixed alpha olefins, resulting in a product with a kinematic viscosity at 100 degrees Celsius ranging from 1 cSt to 1000 cSt.
