Abstract: Methods and apparatus are provided for igniting, modulating, and sustaining a plasma for various plasma processes and treatments. Such treatments include cleaning and sterilizing parts. In some embodiments, a plasma is ignited by subjecting a gas in a multi-mode processing cavity to electromagnetic radiation having a frequency between about 1 MHz and about 333 GHz in the presence of a plasma catalyst. A part can be cleaned by, for example, inserting hydrogen into the plasma and exposing the part to the hydrogen-enriched plasma. A part can be sterilized by heating the part with the plasma.

Abstract: Novel amine terminated bisaspartimides, especially 4,4'-bis{N.sup.2 -[4-(4-aminophenoxy)phenyl]aspartimido}diphenylmethane are prepared by a Michael-type reaction of an aromatic bismaleimide and an aromatic diamine in an aprotic solvent. These bisaspartimides are thermally polymerized to yield tough, resinous polymers cross-linked through --NH-- groups. Such polymers are useful in applications requiring materials with resistance to change at elevated temperatures, e.g., as lightweight laminates with graphite cloth, molding material prepregs, adhesives and insulating material.
