Title: Nancy J Drake: Innovator in Hydrophilic Polymer Compositions
Introduction
Nancy J Drake is a notable inventor based in Painesville, OH (US). She has made significant contributions to the field of polymer chemistry, particularly in the development of hydrophilic copolymers for use in contact lenses. With a total of 3 patents to her name, her work has had a lasting impact on the industry.
Latest Patents
Drake's latest patents include innovative compositions that enhance the performance of contact lenses. One of her key inventions is a hydrophilic copolymer composition that contains a major portion of polymerized units of hydroxyalkyl acrylate or methacrylate monomers. This composition also includes a minor portion of a nitro-substituted aryl acrylate or methacrylate monomer, and optionally, a minor amount of an alkylene glycol diacrylate or methacrylate as a cross-linking agent. These copolymers are produced through a free radical polymerization mechanism or by gamma radiation of the reaction mixture. They are particularly beneficial as soft contact lens materials due to their resistance to clouding and discoloration during use.
Another significant patent involves surface-treated soft contact lenses. In this invention, a hydrophilic polymer-shaped article is treated to create a modified, less hydrophilic polymeric structure on its surfaces. This modification inhibits the penetration of proteins and other substances in the eye environment, significantly reducing the development of clouding and discoloration of the lens material during use.
