Photogenerated base as catalyst for imidization reactions - A new design of photosensitive polymers
Abstract
The photogeneration of free amines or diamines from soluble organic precursors such as photoactive 2-nitrobenzyl carbamates is useful for the imidization of polymers containing amic acid or amic ester moieties. The base-catalyzed reaction occurs at lower temperatures than the non-catalyzed thermal process and is applicable to the patterning of polymer coatings or thin films. © 1993 Springer-Verlag.
