Abstract : This report covers the results of investigations directed towards the development of polyimides and polyaromatic melamine (NCNS) resins for the fabrication of high performance composites for structural applications. In Part I of this investigation polyimide precursors terminated with 5- norbornene groups were processed at 550 deg F. The curing reaction involved the retro Diels Alder reaction followed by the addition polymerization currently in use with PMR-15 and LARC-160M polyimides. jg p.10
