Title: John P. Fouser: Innovator in Acrylonitrile Polymer Technologies
Introduction
John P. Fouser is a notable inventor based in San Francisco, CA, recognized for his contributions to the field of acrylonitrile polymer compositions. With a total of 3 patents to his name, he has made significant advancements in the methods and applications of polyacrylonitrile.
Latest Patents
Fouser's latest patents focus on innovative processes involving acrylonitrile polymer compositions. One of his key inventions details a method for mixing a fugitive plasticizer, such as ethylene carbonate, with moist particulate polyacrylonitrile. This process allows for the removal of water, enabling the adjustment of melt viscosity for the extrusion of polyacrylonitrile into various forms, including film, fiber, pellets, and shaped articles. The stretching and heating of the extruded materials lead to the exudation and vaporization of the fugitive plasticizer, which also carries away any remaining acrylonitrile monomer. The resulting products exhibit significantly increased molecular weight, enhancing their tensile strength and barrier properties. Additionally, this process facilitates the production of polyacrylonitrile foam products. His patents also introduce a novel cross-linking agent for polyacrylonitrile, divinyloxybutane, along with thermostabilizing agents such as N-maleimides and stilbene derivatives.
