Patent number: 4431792Abstract: The compounds are of the class of aromatic polyamides useful as matrix resins in the manufacture of composites or laminate fabrication. The process for preparing this thermoplastic-thermoset polyamide system involves incorporating a latent crosslinking moiety along the backbone of the polyamide to improve the temperature range of fabrication thereof wherein the resin softens at a relatively low temperature (.congruent.154.degree. C.) and subsequently "sets-up" or undergoes crosslinking when subjected to higher temperature (.congruent.280.degree. C.).Type: GrantFiled: December 7, 1982Date of Patent: February 14, 1984Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Terry L.
