Abstract
The present invention provides PMR-type polyimides that exhibit lower melt viscosities than PMR-type polyimides of the prior art. These PMR-type polyimides are created by incorporating flexible linkages, such as kinked structures and twisted or non-coplanar moietes into the backbone structure of the PMR. Specifically, the present invention provides for the production of PMR-type polyimides having 2,2′-disubstituted biaryls in the polymer backbone.
