ABSTRACT:
Degradable polyimides are prepared in high yield by polymerizing a monomer containing at least two anhydride groups, and a monomer containing at least two primary amine groups and at least one acidic group, in bulk or in a solvent. The polyimides are very strong in terms of their mechanical properties, yet degradable under standard physiological conditions.
