Title: The Innovations of Norman Fishman
Introduction
Norman Fishman is a notable inventor based in Menlo Park, CA. He has made significant contributions to the field of polymer science, particularly in the development of acrylonitrile polymer compositions. With a total of 6 patents to his name, Fishman's work has advanced the understanding and application of polyacrylonitrile materials.
Latest Patents
Fishman's latest patents focus on innovative processes involving acrylonitrile polymer compositions. One of his key inventions describes 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 extrusion 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. Fishman has also disclosed a novel cross-linking agent for polyacrylonitrile, known as divinyloxybutane, along with thermostabilizing agents such as N-maleimides and stilbene derivatives.
