ABSTRACT:
The substrates of the present invention comprise a polyimide base polymer derived at least in part from non-rigid rod monomers together with optionally rigid rod monomers where the substrates are cured under low tension. The resulting polyimide materials have been found to provide advantageous properties (e.g. balanced molecular orientation, good dimensional stability, and flatness) particularly useful for electronics type applications.
