| Abstract: | The post crosslinking reaction parameters were systematically studied for the investigation on formation mechanism of oxygen containing groups on the surface of hypercrosslinked polymers. The FT-IR spectra and the Boehm titration were employed to characterize the surface chemistry of the synthesized polymers. The GC-MS was used to analyze the nitrobenzene that was the solvent in the reaction. The functionalities for example carbonyls were formed through the oxidation of chloromethyl groups by nitrobenzene and the carboxylic groups were formed through further oxidation by oxygen during the synthesis process. Meanwhile the nitrobenzene was deoxidized to aniline. |
