用透射电子显微镜和计算机模拟手段研究了含间苯连接的聚醚醚酮酮（ＰＥＥＫｍＫ）聚合物的结晶结构，结果表明，ＰＥＥＫｍＫ单胞是由两个具有镜像关系的分子链组成，分子链为平面锯齿构像，平均锯齿角和二面角分别为１２６°和３０．２°。由电子衍射结果计算出单胞参数为：ａ＝０．７９３ｎｍ，ｂ＝０．５９０ｎｍ，ｃ＝０．９７９ｎｍ。
The crystal structure of PEEKmK polymer containing isophenylene was investigated by transmission electron microscopy and computer simulation. The results showed that PEEKmK monomer consists of two molecular chains with mirror image relationship Flat zigzag conformations with an average zigzag angle and dihedral angle of 126 ° and 30.2 °, respectively. The unit cell parameters calculated from the electron diffraction results were: a = 0.793 nm, b = 0.590 nm, c = 0.979 nm.
