Title: The Innovative Journey of Barbara J Ringrose
Introduction
Barbara J Ringrose is a distinguished inventor based in Swindon, GB, renowned for her contributions to the field of polymer chemistry. With two patents to her name, Ringrose has made significant advancements, particularly in the development of hydrophilic water-swellable graft polymers.
Latest Patents
Ringrose's most recent patents include processes for preparing high-performance hydrophilic, water-swellable graft copolymers. The first patent describes a graft copolymer consisting of polyethylene vinyl acetate (PEVA) with 8 to 30 wt. % vinyl acetate units. This innovative copolymer is radiation-graft copolymerized with an ethylenic carboxylic acid and heat-treated in an aqueous hydroxide solution above PEVA's softening point, yielding polymers that are particularly effective for medical devices. Applications of these polymers include surgical devices such as laparoscope tubes, urethral catheters, and endovascular cannuli.
Her second patent focuses on a method for treating hydrophilic polymer films. This method involves immersing the films in a swelling liquid at temperatures above 80°C, after which the treated films exhibit reduced electrical resistance and increased hydroxyl ion permeability. These improved properties make them suitable for applications as battery separators and in other semi-permeable membrane systems.
