Abstract Previous work in our laboratory has shown that covalent bonding of a semiflexible polymer in a bis‐imide matrix prior to thermal polymerization is a promising, although structure‐dependent, approach to the synthesis of molecular composites from organic solvents in thermosets. In the present investigation, the focus has been on the rapid amine‐catalyzed anionic polymerization and crosslinking of fluorine‐containing bis‐maleimides. The objective has been to provide physical entrapment of rigid polymer prior to aggregation. Results have shown that gelation of fluorine‐containing bis‐maleimides initiated by tertiary amines in organic solvent can occur in seconds at moderate temperatures, and thus affords a means of preventing aggregation of rigid polymer prior to crosslinking.
