On the basis of the Frontier Orbital Theory and three Bonding Principles, the possibility of reaction of active HOSA^- carbanion on polymerization process of MA by alkali catalyst and the mechanism of anionic polymerization of maleic anhydride were studied.

Such cases as hydride ion transfer from reduced nicotinamide coenzymes or the carbanion generated by base abstraction of a substrate proton may lead to attack at the flavinN-5 positions; some nucleophiles, such as the hydrogen peroxide anion, are added on the C-4a position with its frontier orbital.

从减少烟酰胺辅酶或基片基抽象所产生的质子氢离子负离子转移这种情况可能会导致攻击的flavinN - 5的位置；例如过氧化氢负离子一些亲，被添加在C - 4A条位置其前线轨道

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. Theanionic and radical polymerization of MA discussed also. Theoreticalstudies show that both polymerization products of MA are in the chainstructures, corresponding to the experimental findings.

第二部分用量子化学AM1方法，计算研究了马来酸酐的基态和激发态电子结构；应用前线轨道理论和成键三原则分别探讨了碱催化条件下和羟基自由基引发下马来酸酐均聚合过程中α-羟基丁二酸酐碳阴离子和α-羟基丁二酸酐碳自由基活性中间体参与反应的可能性及由它们引发的马来酸酐阴离子聚合反应机理和自由基引发聚合反应机理；理论研究表明马来酸酐的均聚合产物均为链式结构，与实验事实相相符。
