Title: The Innovative Contributions of David J Farrar
Introduction
David J Farrar is a notable inventor based in London, GB. He has made significant contributions to the field of polymer science, holding a total of four patents. His work primarily focuses on the development of novel polymeric compositions and their applications in various industries.
Latest Patents
Farrar's latest patents include "Polymeric compositions and their production and uses," which describes a clear personal care or other aqueous gel formed from dry polymer particles. These particles are free of materials that render the gel cloudy and are produced through reverse phase emulsion polymerization. The process involves distilling water from the emulsion while using a sufficient amount of non-aqueous liquid to prevent emulsion breakage. The polymer particles are then washed with isopropanol or another suitable solvent before the solvent is evaporated. Another significant patent is "Polymers, their production and uses," which introduces novel polyvinyl alcohols that contain vinyl units with pendant hydrophobic groups in the polymeric backbone. These polymers are synthesized by hydrolyzing corresponding polyvinyl acylates under conditions that avoid hydrolysis of the pendant hydrophobic groups. The hydrophobic units serve as internal plasticizers, enhancing the viscosity and rheological characteristics of aqueous compositions formed from the polymer.
Career Highlights
Throughout his career, Farrar has worked with various companies, including Molins Plc. His expertise in polymer science has allowed him to contribute to advancements in personal care products and other applications.
Collaborations
Farrar has collaborated with notable individuals in his field, including Robert E Williams and Robert William Davies. These collaborations have likely enriched his research and development efforts.
