Title: The Innovations of Donald W. Pennington

Introduction

Donald W. Pennington is a notable inventor based in Baton Rouge, LA (US). He has made significant contributions to the field of polymer chemistry, particularly in the oxidation of halogenated polymers. With a total of 7 patents to his name, Pennington's work has had a lasting impact on the industry.

Latest Patents

One of his latest patents focuses on the oxidation of halogenated polymers and anticaking halogenated polymers. This innovative process involves forming an admixture of an acidic oxidizing agent and a suspension of a particulate halogenated polymer in a polar liquid. The admixture is then heated to a temperature sufficient to initiate the reaction between the polymer and the oxidizing agent. The reaction continues until an oxidized polymer with a preselected extent of oxidation is obtained. Additionally, at least one addition polymerizable compound can be grafted to the oxidized halogenated polymer. The resulting oxidized halogenated polymer and its graft copolymers exhibit physical properties that differ from those of the original halogenated polymer, with certain graft copolymers being non-caking or free-flowing.
