Abstract: A process including shearing a first dispersion medium and a second dispersion medium under conditions that precipitate a plurality of polymeric fibers; and collecting the plurality of polymeric fibers at a rate of at least 300 grams/hour. The first dispersion medium is a solution including at least one polymeric component. The at least one polymeric component includes a polyetherimide component selected from the group consisting of polyetherimide homopolymers, polyetherimide co-polymers, polyetherether ketones homopolymers, polyetherether ketones copolymers, polyphenylene sulfones homopolymers, polyphenylene sulfones copolymers, and combinations thereof. Products produced by the process can be non-woven paper, medical implants, ultra-fine filters, membranes, hospital gowns, electrical insulation paper, honeycomb structures and personal hygiene products, dialyzers, blood, oxygenator filters, intravenous (IV) filters, diagnostic test filters, and blood/apheresis filters.

Abstract: A method for preparing a high temperature melt integrity separator, the method comprising spinning a polymer by one or more of a mechanical spinning process and an electro-spinning process to produce fine fibers.
