NASA Langley Research Center in Hampton, VA solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed series of polyimide thermosets that are highly heat resistant, as well as moisture and chemical resistant. RP-50 polyimides are similar to the successful RP-46 series of polyimides, except that rather than being used for structural composites, RP-50 polyimides are best utilized as high temperature coatings, adhesives, thin films, or composite matrix resins. Beyond high temperature resistance, RP-50 polyimides have many other advantages over comparable materials, such as excellent adhesion properties and the fact that they are manufactured from readily available raw materials. RP-50 can withstand repeated instantaneous temperature surges at temperatures up to 600 degrees Celsius. It does not swell or degrade when exposed to hydraulic fluids, jet fuels, lubricating oils, strong cleaning solutions or seawater. RP-50 has excellent adhesion to a wide variety of metallic, ceramic and other non-metallic substrates. It has application as high temperature coatings, adhesives, thin films, and as composite matrix resin. The polyimides are prepared by reacting a mixture of compounds including (a) 3,3',4,4'-benzophenonetetracarboxylic dianhydride (BTDA), (b) 3,4'-oxydianiline (3,4'-ODA), and (c) 5-norbornene-2,3-dicarboxylic anhydride (NA) in a high boiling, aprotic solvent to give 5 to 35% by weight of polyamic acid solution. The ratio of (a), (b), and (c) is selected to afford a series of polyimides having different molecular weights and properties. Using a two-step condensation method, the mixture first forms a polyamic acid precursor. Upon heating at or above 300 C, the polyamic acids then form polyimides, which are particularly suitable for use as a high temperature coating, adhesive, thin film, or composite matrix resin.
