ABSTRACT:
Soluble, film-forming, polyamides, polyimides, and polyamide-imides and their copolymers made using 3,5-diamino-t-butylbenzene are described. These polymers have some solubility in organic solvents such as N-methylpyrrolidone, a high Tg, excellent thermal stability, lower density and lower moisture uptake and are useful in films, fibers and composites, and in the electronics industry as electrical component substrates, protective coatings, interlevel dielectrics and the like.
