摘要: 利用AM1方法对聚醚醚酮模型化合物全优化,结果为:芳环平均相互扭转角为33.0°,桥键角117.0~118.0°;其分子结构拓扑图形表明:所有苯环(核)为平面构型,但其内角扭曲;其氢原子对苯环(核)构型无实质性贡献。在更长链的计算中,冻结苯核与氢原子也得出满意结果。根据Mulliken键序与电荷讨论了醚交换与磺化反应。

Abstract: In this paper,full optimization of poly(aryl ether ether ketone)s model compound by using AMI semiempirical method was made,the results showed that this rigid chain polymer has greater rotation and torsion on its bridge-bonds, the average torsion angle of 33.0°on its two aromatic-rings was found, while its average bridge-bond angle was in the range from 117.0°to 118.0°.Bridge angles at both ether and carbonyl ere found to be approximately equal.Research on topological pattern for polymer chain was showing that the polymer aromatic-ring were not greatly deviated from the ideal geometry except bridge-bonds, which is of much importance for further calculation of the polymer with longer molecular chain and based on the Mulliken bond order and charges,the disscusion of ether exchange and sulphonation reaction was given.

Key words: AM1, Model compound, Full optimization, Bond order and charges
