In order to produce polyimide films in situ on silicon substrates, while minimizing the thermally induced residual stresses on cooling from the cure temperature, we have prepared various polyimidepolydimethylsiloxane based block copolymers derived from pyromellitic dianhydride (PMDA) and p,p'oxydian
## SYNOPSIS Control of the internal morphology of wet-spun fibers from a fluorinated polyimide has been achieved by varying the rate of polymer coagulation through adjustments in nonsolvent/solvent miscibility and precipitation strength of the coagulation bath. Filament internal morphologies range
