Title: The Innovations of Andrew Leonard Tipton

Introduction

Andrew Leonard Tipton is an accomplished inventor based in Woburn, MA (US). He has made significant contributions to the field of polymer science, particularly in the development of cross-linked polymers. His innovative work has led to advancements in materials that exhibit improved physical properties.

Latest Patents

Tipton holds a patent for a method of cross-linking poly(ethylene oxide) and poly[oxymethylene-oligo(oxyethylene)](PEM) disks through exposure to UV radiation. The patent describes how the rate of formation of cross-links is greatly enhanced by the presence of benzophenone. This process allows for an average cross-link density of up to 6 mol% of ethoxy units after irradiation. The resulting highly cross-linked polymers are insoluble in water or organic solvents, showcasing improved physical properties for handling and the formation of free-standing films. Dynamic modulus measurements and polymer swelling are employed to characterize these polymers, revealing that upon irradiation, PEO and PEM transform into cross-linked elastomeric solids.
