Title: Arthur H Gilbert: Innovator in Polymer Chemistry
Introduction
Arthur H Gilbert is a notable inventor based in Stockton on Tees, GB. He has made significant contributions to the field of polymer chemistry, holding a total of 3 patents. His work primarily focuses on the production and handling of advanced polymer materials.
Latest Patents
One of his latest patents involves the production and/or handling of aryl polyethers and thioethers polymers. This innovative process allows for the creation of polyarylethersulphones or polyaryletherketones by reacting phenols with aromatic halogen compounds. The raw polycondensation product is treated to remove alkali halide by adjusting its composition and/or temperature, enabling it to dissolve in water and hold the polymer in solution. This solution is then contacted with hot water, preferably under pressure, to facilitate the desired chemical reactions.
Another significant patent by Gilbert is a dimerization process for acrylonitrile. This process converts acrylonitrile into dicyanobutene and methylene-glutaronitrile using a phosphinite or phosphonite catalyst. The method employs a solvent mixture of proton-donating organic solvent, aromatic hydrocarbon solvent, and aliphatic hydrocarbon solvent in a specified ratio. This innovative approach aids in product isolation through phase separation or liquid/liquid extraction.
