Xrd test results showed that pp polymer chains have intercalated lays of ommt among the series pp - b . tem observed that ommt was stripped and close to the single layer of slices ; among the series pp - a , the characteristic diffraction peak of ommt still appeared the original position , which prove pp polymer chains were too difficult to intercalate directly lays of ommt , tem observed that ommt have serious reunion phenomenon and the majority exist by form who regiment form a cluster Xrd测试结果表明： pp - b系列中的pp高分子链已经插层进入到有机蒙脱土的片层间， tem观察有机蒙脱土大部分被剥离成接近单层片状； pp - a系列中，有机蒙脱土的特征衍射峰仍出现在原位置，说明pp大分子链很难直接插入蒙脱土片层间， tem观察有机蒙脱土较严重的团聚现象，大部分以团簇的形式存在。
