In the second part, quantum chemical AM1 methods were employedto theoretically investigate the electronic structures of maleic anhydride in ground- and excited-states. On basis of the frontier orbital theoryand three bonding principles, the possibility of reaction of active α-hydroxysuccinic anhydride carbanion and active α-hydroxy-succinic anhydride radical on polymerization process of MArespectively by alkali catalyst and by hydroxyl radical was discussed.
