Title: Innovations by George H. Greene: A Pioneer in Silicone Polyether Copolymers

Introduction

George H. Greene, an esteemed inventor based in Croton-on-Hudson, NY, has made significant contributions to the field of polymer chemistry. With eight patents to his name, Greene's work focuses on innovative silicone polyether copolymers that serve essential functions in polyurethane foam production.

Latest Patents

One of Greene's latest patents features novel compositions of silicone/polyether block copolymers. These innovative surfactants play a critical role in several classes of polyurethane foam production. Unlike conventional copolymers, which have a polysiloxane backbone with pendant polyethers, Greene's invention reverses this structure, featuring siloxane pendants on a polyether chain. These non-hydrolyzable polysiloxane polyoxyalkylene copolymers are characterized by their inverted structure, with polyoxyalkylene backbones that have lateral and/or terminally pendant polysiloxanes. They present a narrow molecular weight and compositional distribution and are free of unreacted polyether or non-modified silicone oil diluent. The surfactants developed by Greene are not only beneficial in various urethane foam systems but also exhibit aqueous wetting properties.

Career Highlights

Throughout his career, George H. Greene has worked with prominent organizations, including Union Carbide Corporation and Union Carbide Chemicals and Plastics Company, Inc. His innovative work has significantly influenced the development of advanced materials in the chemical industry.
