Making Semicrystalline Polyimide PowdersSemicrystalline polyimides with controlled molecular weights synthesized in process that yields polyimides in powder form. Powders with desirable melt-flow properties formed in reaction vessels, without grinding. Commercially attractive for fabrication of adhesive bonds, compression molding of shaped parts, and deposition onto reinforcing fibers for subsequent hot pressing into polyimide-matrix/fiber composites.
