ABSTRACT:
A process was developed to prepare 1,3-diamino-5-pentafluorosulfanylbenzene. This process involved two steps: preparing the dinitro compound, 1,3-dinitro-5-pentafluorosulfanylbenzene, and reducing this compound to form the corresponding diamine. This diamine was reacted with various dianhydrides, diacidchlorides, and epoxy resins to form polyimides, polyamides, and crosslinked epoxies. These polymers were used to prepare semi-permeable membranes, wire coatings, and films.
