Patent number: 8715545Abstract: The present systems and methods utilize a polyamic acid solution as a precursor to form a polyimide bead having desired properties. The polyamic acid solution may be formed into a polyamic acid droplet. The polyamic acid droplet is then processed to form a polyamic acid bead, such as by extraction of solvent to concentrate the polyamic acid or by partial chemical imidization of the polyamic acid. The polyamic acid bead is then better able to retain its shape during subsequent processing steps, such as drying and pressurizing, before final thermal imidization.Type: GrantFiled: September 3, 2010Date of Patent: May 6, 2014Assignee: ExxonMobil Upstream Research CompanyInventors: Dennis G.
