| 摘 要： | The steric tacticity of polyphenylsilsesquioxanes is discussed based on both structure transformation consideration and the results of calculations, X-ray diffraction patterns, fluorescence emission spectroscopy, and scanning electron microscopy. All of the results show that cis-isotactic conformation is the most probable one for ladderlike polymer polyphenylsilsesquioxane though other conformations such as cissyndiotactic may also be present in the macromolecules depending upon the preparation conditions.
