POLYIMIDE POLYMER FROM NON-STOICHIOMETRIC COMPONENTS

摘要

A process for adjusting polyimide polymer properties includes combining monomers in a reaction mass to form a polyimide precursor. A property modifying moiety which is covalently bonded to an amine is then added to the reaction mass, and the reaction between the amine bonded to the property modifying moiety and the polyimide precursor is arrested before equilibrium. The polyimide precursor is imidized to form a polyimide polymer prior to equilibrium. The property modifying moiety can be evenly dispersed in the resulting polyimide polymer
