โœฆ Synopsis

Two linear polyimides were subjected to accelerated isothermal aging at temperatures between 300 and 400ยฐC. Losses in toughness correlated well with changes in glass transition temperature (T,) of the films, but not with weight loss. Both materials have extrapolated lifetimes of 100,000 h near their !/'is.
