  • Process for making thick multilayers of polyimide
    Patent number: 5137751
    Abstract: A polyimide layer having a thickness greater than about 5 microns is formed on a substrate by coating a substrate with a solution of polymer and a solvent of the formula ##STR1## wherein R.sub.1 and R.sub.2 are independently a hydrogen, a C.sub.1 to C.sub.6 alkyl moiety, or a ##STR2## R.sub.5 is a C.sub.1 to C.sub.6 alkyl moiety; and R.sub.3 and R.sub.4 are independently hydrogen or a C.sub.1 to C.sub.6 alkyl moiety, and curing the resulting coated substrate.
