Safe process for making polymers containing N-phenylimide groups |
摘要 |
Polymers containing N-phenylimide groups are made by reacting polymers containing succinic or glutaric anhydride groups with a substituted or unsubstituted aminobenzoic acid in a devolatilizing extruder at a barrel temperature of about 180° to about 320° C., whereby complete decarboxylation takes place during the formation of the N-phenylimide groups.
