ABSTRACT:
Cyclic dianhydrides and polyimides are prepared from maleic anhydride compounds and diolefins. The diolefins are alpha- , omega-linear diolefins of up to 100 carbon atoms or cyclic diolefins of up to 40 carbon atoms. The polyimides and copolyimides prepared from these cyclic dianhydrides are useful in films, fibers and coatings.
