Abstract:
Cross-linked polymers comprising an anhydride or partially hydrolyzed anhydride functionalized polymer having oligomeric polyamic acid cross-links are provided. In solution, a polymer of the invention forms a formable gel. The formable gel is useful for forming shaped articles that are useful for electronics applications.
