Soluble and cross-linkable polyimides from a vanillin-derived diamine: preparation, post-polymerization and properties

A novel trifluorovinyl-ether (-OCF&z.dbd;CF 2 , TFVE) functionalized diamine ( DA-TFVE ) with a triarylmethane structure was successfully obtained from renewable vanillin through a Brønsted acidic ionic liquid catalyzed Friedel-Crafts reaction. Subsequently, traditional two-step condensations be...
