ABSTRACT:
Substantially fully imidized polyimidesiloxanes which are based on a selected pyridine compound are soluble in diglyme which gives them particular utility in the micro-electronics industry. The polymers are prepared from the dianhydride, a difunctional siloxane monomer and an organic diamine that has the formula ##STR1## wherein X is hydrogen, halogen, phenyl or combinations thereof,
