Polyetherimides prepared by self-condensation of hydroxyaryl phthalimide salts

摘要

Polyetherimides are provided which are based on the self-condensation in a dipolar aprotic solvent of a hydroxyaryl phthalimide salt having a nuclear bound leaving radical on the phthalimide ring. The polyetherimides are injection-moldable high performance thermoplastics.
